TPS82130SILR Detailed Description

The TPS82130 MicroSiP power module is a synchronous step-down converter that uses DCS-Control. This cutting-edge regulation topology merges the best features of voltage-mode control and hysteretic. The DCS-Control topology uses pulse width modulation (PWM) under moderate to high loads and power saving mode (PSM) with low currents.

The converter operates in PWM mode with a nominal switching frequency of 2.0 MHz that varies over the input voltage range. The converter enters a power-saving mode as the load current drops, decreasing the switching frequency and limiting the quiescent current of the IC to maintain a high-efficiency level across the whole load current range. DCS-Control’s ability to go from PWM to PSM using a single construction block results in a smooth transition with no change to the output voltage. The TPS82130 has low output voltage ripple, excellent DC voltage regulation, and load transient regulation, all reducing interference with RF circuits.

TPS82130SILR Feature Description

● Switch Current Limit

The switch current limit also slows down the high inductor current and too much current draining from the battery or the input voltage rail. A shorted output circuit or a heavy load can cause an excessive current. Once the inductor’s top current reaches the switch’s current limit, the high-side FET is turned off, and the low-side FET is turned on to ramp down the inductor’s current. This usually takes 30 ns.

● Undervoltage Lockout

The device was made with an undervoltage lockout system to work better and stop problems when the input voltage is low. This feature, which has a hysteresis of 200 mV, will turn off the device electrically if the voltage goes below VUVLO. The input voltage range of the TPS82130SILR Non-Isolated PoL Module DC-DC Converter with 1 outlet is 3V to 17V, an output voltage range of 0.9 to 5V, and an output current of up to 3A.

● Thermal Shutdown

The TPS82130SILR Non-Isolated PoL Module DC-DC Converter is made to prevent heat damage by shutting down when the junction temperature (TJSD) goes above a certain level. Once this happens, the move will no longer work. But once the device’s temperature drops below the threshold by 20°C, it will return to normal operation immediately.

• From 3 V to 17 V can be put in.
• 3-A constant output current.
• Topology for DCS-Control.
• Use the power save mode when you don’t need much power.
• 20-µA working quiescent current.
• 9-V to 6-V changeable output voltage.
• For the last failure, use a 100% duty cycle.
• A good amount of power.
• A soft start-up that can be programmed and tracked.

TPS82130SILR Functional Modes

● Enable and Disable (EN)

Setting the EN pin to a logic High turns the gadget on. So, shutdown mode is forced if the EN pin is pulled low with a normal shutdown current of 1.5 A. When the EN pin is Low, it is linked to an internal 400-k pulldown resistor. When the EN pin is High, the pulldown resistor is no longer linked.

● Soft Start-Up (SS/TR)

The internal voltage clamp controls the output voltage drop during start-up. This keeps the inrush current from being too high and ensures that the output voltage rises at a controlled rate. When the EN pin is pulled high, the device starts switching after a delay of about 55 s, and the output voltage rises at a rate set by an external capacitor connected to the SS or TR pin. Using a very small capacitor or leaving the SS or TR pin free achieves the fastest start-up time.

The TPS82130 can start with an output capacitor that has already been charged. During the pre-biased start-up, neither power MOSFETs can turn on until the internal voltage clamp sets the output voltage higher than the pre-bias voltage. When the device is in shutdown, undervoltage lockout, or thermal shutdown, an internal resistor drains the capacitor tied to the SS/TR pin. When you go back to those states, a new start-up process begins.

● Power-Good Output (PG)

The device has a sound power output (PG). The PG pin has a high impedance when the output is above 95% of the normal voltage. The PG pin is driven low when the output voltage exceeds 90% of the standard voltage. The PG pin can sink up to 2 mA of current and is an open-drain output. A pull-up resistor must be connected to any voltage rail lower than 6 V for the power sound output.

Layout

● Layout Guidelines

TI suggests putting all parts as close to the IC as possible. The input capacitor must be placed so that it is closest to the device’s VIN and GND pins.

To cut down on parasitic inductance and resistance, use wide and short traces for the main current routes.

To help the device get rid of heat better, the exposed thermal pad must be linked with vias to the bottom or internal layer ground planes.

● Thermal Consideration

When the TPS82130 runs at a high outdoor temperature or puts out a lot of power, the output current must be lowered. The amount of current derating depends on the incoming voltage, the output power, the PCB layout design, and the environment’s thermal conditions. Care must be taken especially when the PCB temperature in a certain area is higher than 65°C. The temperature of the TPS82130 module must be kept below 125°C, the highest temperature it can handle. Here are three simple ways to improve thermal performance:

• Make the PCB design better at getting rid of power.
• Change how the TPS82130 connects to the PCB in terms of heat.
• Bring in some air to the machine.

To get a rough idea of the TPS82130 module’s temperature, take the typical efficiency from this data sheet and apply it to the desired application situation to find the module’s power dissipation. Then, multiply the power lost by the module by its thermal resistance to get the rise in temperature.

Conclusion

In conclusion, the TPS82130SILR DC-DC converter is a highly efficient and flexible power module with excellent control and low output voltage ripple. This makes it a great choice for powering RF circuits. Its wide input voltage range, switch current limit, undervoltage lockout, and other features make it a safe choice for many power supply designs. To get the best performance, it is important to follow the suggested layout and thermal factors.
