Texas Instruments TPS62085RLTR

TPS62085RLTR Description



The TPS62085RLTR is a high-frequency synchronous step-down converter with a small footprint and great efficiency. Common battery technologies are supported with input voltages ranging from 2.5 V to 6.0 V.

The devices are designed to provide high-efficiency step-down conversion across a wide range of output currents. To maintain high efficiency across the whole load current range, the converter runs in PWM mode for medium to heavy loads and immediately switches to Power Save Mode at light loads.

The internal compensation circuit provides a wide range of external output capacitor values from 10μF to 150μF to satisfy the needs of the system power rails. Excellent load transient performance and output voltage regulation accuracy are accomplished through the use of its DCS-Control architecture. The devices come in a VSON packaging with a 2-mm by 2-mm pitch.
