TPS62163DSGR Description

The TPS6216x device family is made up of user-friendly synchronous step-down DC/DC converters that were created with the intention of meeting the needs of applications that demand a high-power density. The DCS-ControlTM architecture allows for low-profile inductors with a high switching frequency of approximately 2.25 MHz. The quick reaction to transients and precise output voltage are both made possible by the fast switching frequency. Because to their wide operating input voltage range of 3 V to 17 V, the devices are well-suited for use in systems that are powered by a Li-Ion or other battery or by 12-V intermediate power rails. It has a wide operating voltage range of 0.9 V to 6 V and can maintain a constant output current of 1 A at a duty cycle of 100%.

You can also set up the enable and open-drain power good pins to create power sequencing in your application. With the power-saving mode engaged, the devices’ VINs shows a quiescent current of about 17 A. Automatically and unobtrusively, the power-saving mode kicks in when the load is low, and it maintains the same degree of efficiency across the whole load range. When in shutdown mode, the device’s current draw lowers to less than 2 microamperes, effectively turning it off. The part is available in a 2-millimeter-by-2-millimeter (DSG) 8-pin WSON package or a 3-millimeter-by-3-millimeter (8-pin) VSSOP package, depending on the output voltage type. Measurements of 3.00 mm x 3.00 mm were taken from both packets (DGK).

Detailed Description

Combining the benefits of hysteretic, voltage mode, and current mode control as well as an AC loop directly associated with the output voltage, the TPS6216x synchronous step-down DC/DC converters are based on DCS-ControlTM (Direct Control with Smooth transition into power save mode). Changes in the output voltage are fed into a quick comparator stage via this control loop. It determines the switching frequency, which remains unchanged under steady-state conditions, and allows instantaneous reactions to transient changes in the load. Accurate DC load regulation is accomplished using a voltage feedback loop. The internally corrected regulation network guarantees fast and steady functioning, which uses minimal additional parts and low ESR capacitors.

Medium and heavy loads can be handled by DCS-PWM Control’s mode, while the topology’s power-saving PWM mode can handle low loads. In pulse width modulation mode, it switches at its nominal switching frequency while in continuous conduction mode. On average, this frequency is 2.25 MHz, with a small, manageable range of input voltage-dependent frequency variation. The converter enters power save mode whenever the load current drops to maintain high efficiency even at very light loads. To conserve energy, the switching frequency in this mode falls linearly with the current draw.

Since DCS-ControlTM accommodates both modes of operation within a single building block, switching between PWM and power-saving mode is smooth and does not influence the output voltage. Versions with a constant output voltage have the fewest external parts (three) and the lowest current draw (one). The maximum nominal output current is 1 A, supported by an internal current restriction. The TPS6216x family provides very low output voltage ripple, excellent DC voltage regulation, and superior load transient regulation to reduce interference with RF circuits.

Feature Description

Turn on and Power Down (EN) It begins functioning when enable (EN) is set to a high value. If EN is pulled low, a shutdown current of about 1.5 A is drawn to induce a shutdown. Shutdown involves disabling all control logic and powering down the onboard MOSFETs. The output voltage is gradually reduced by the built-in resistive divider. To prevent bouncing, a low EN pin is connected to an internal pull-down resistor of roughly 400 k. The EN pin allows numerous power rails to be sequenced by connecting to an appropriate output signal from another power rail.

● Current Limit and Short Circuit Protection

The devices in the TPS6216x series are safe from damage caused by overload and short circuits. The current limit determines the maximum output current when the load is high. The high-side FET is disabled if the current limit is exceeded. Turning on the low-side FET prevents a shot-through current and allows the inductor current to drop. Whenever the low-side FET current drops below the low-side current limit threshold, usually 1.2 A, the high-side FET turns on again. This gadget’s current restriction regulates how much current it can emit (see Electrical Characteristics). It is possible for the actual current to surpass the static current limit for a brief period of time due to internal propagation delay. Here is how the dynamic current limit is determined:

● Power Good (PG)

If the output voltage from the TPS6216x has been properly set, the power good (PG) function will light up. Several railways’ beginning sequences can be coordinated using the PG signal. For use without a pull-up resistor, the PG pin is an open-drain output (to any voltage below 7 V). Maintaining its logic low level requires a current sink of 2 mA. Once the device is turned off via EN, UVLO, or thermal shutdown, the interface presents a high impedance. The PG pin should be grounded to GND when in use; however, it can be left floating when not in use.

● Undervoltage Lockout (UVLO)

Under-voltage lockout protects against accidental operation by turning off both power FETs if the input voltage dips below a certain threshold. A minimum of 2.7 V is usually used as the under-voltage lockout threshold. When the input voltage is below the UVLO threshold, the device shuts off, but when it is above, it operates normally. Once the input voltage rises above the threshold by the hysteresis value, usually 180 mV, the converter restarts.


In conclusion, Texas Instruments’ TPS62163DSGR DC to DC converter is the best option for satisfying your requirements in this area of power management. This converter is useful for many gadgets because of its flexible voltage output. Power input must be between 3 and 17 volts, and the maximum current from its single output is 1 amp.
