The TPS62085RLTR is a synchronous step-down DC-DC converter that offers excellent efficiency and is manufactured by Texas Instruments. To meet the requirements of a wide range of applications, including smartphones, tablets, and other portable devices, the product has been engineered to deliver a power supply solution that is both space-efficient and high-performing. This tutorial will present an in-depth analysis of the TPS62085RLTR, which will cover its features, characteristics, and optimal working circumstances.
The TPS62086, TPS62085, and TPS62087 devices from Texas Instruments provide high-frequency synchronous step-down converters with compact solution sizes and excellent efficiency. A 2.5 V to 6.0 V voltage input range is offered, making it compatible with various standard battery technologies. Step-down conversion with great efficiency is the primary emphasis of these devices, which can handle a wide range of output currents. The converter runs in PWM mode under medium to heavy loads and enters automatic Power Saving Mode operation when under light loads.
This helps the converter maintain high efficiency over the whole load current range. The internal compensation circuit provides a wide range of options for the values of the external output capacitor, which can be anywhere from 10 F to 150 F. This is done to accommodate the needs of the system power rails. In conjunction with its DCS-Control architecture, it can deliver exceptional load transient performance and accurate output voltage control. The components are offered in VSON packaging with dimensions of 2 millimeters by 2 millimeters.
The TPS62085RLTR has a temperature range of operation that extends from -40 degrees Celsius to 85 degrees Celsius. Nonetheless, it is essential to ensure that the gadget is not exposed to temperatures outside of this range since doing so might negatively impact its functionality and dependability.
The TPS62085RLTR can be used in a wide range of portable power supply configurations, such as:
Using a DCS-Control (Direct Control with Smooth transition into Power Saving Mode) topology, the TPS62085, TPS62086, and TPS62087 are synchronous step-down converters. These advantages of hysteretic, voltage, and current mode control techniques are combined in an advanced regulation topology. Under medium to high loads, the DCS-Control architecture switches to pulse width modulation (PWM) mode, whereas at low loads, Power Saving Mode is activated. With a nominal switching frequency of 2.4 MHz in PWM mode, the converter’s switching frequency is modulated precisely across the input voltage range.
To maintain high efficiency across various load currents, the converter enters a “Power Saving Mode” as the load current drops. The switch from PWM mode to Power Saving Mode is smooth and does not influence the output voltage because DCS-Control allows both operation modes (PWM and PSM) within a single construction block. The fixed-output variant of the solution is the most space-efficient and has the lowest no-load current. In addition to very low output voltage ripple, the devices also provide good DC voltage regulation and superior load transient regulation, so they won’t interfere too much with RF circuits.
Internal soft-start circuitry is present in the TPS62085, TPS62086, and TPS62087, and it gradually increases the output voltage to the nominal value over a period of about 0.8 milliseconds. It prevents output voltage spikes and inrush current from being too high. It also protects primary cells and rechargeable batteries from experiencing voltage drops that are too large. The output capacitor can be biased before the gadget is turned on. Starting at the applied bias voltage, the device gradually increases the output voltage to its maximum.
The switch current limit protects devices from excessive inductor current and current drain from the battery or input voltage rail. In the event of a shorted or saturated inductor, a high output load, or a shorted output circuit, excessive current could flow. The inductor current is ramped down by switching on the low-side MOSFET if the high-side MOSFET is disabled by the inductor current exceeding the threshold ILIM.
After the switch current restrictions have been triggered 32 times, the devices will cease switching and allow the output to drain. The devices will automatically initiate a fresh start-up routine when the standard wait time of 66 s has elapsed. This form of protection against electrical overload is known as HICCUP. In this mode, the devices will keep cycling until the high load condition no longer exists.
The TPS62085RLTR is a high-performance, synchronous step-down DC-DC converter that is suitable for a wide range of portable power supply applications. Its high efficiency, wide input voltage range, adjustable output voltage, and low quiescent current make it an ideal choice for battery-powered devices. The TPS62085RLTR provides a robust and reliable power supply solution with its over-current and thermal shutdown protection.
