The TPS62A01DRLR is a high-efficiency synchronous step-down DC-DC converter manufactured by Texas Instruments (TI). Designed for compact power management applications, this device supports an input voltage range of 2.5V to 5.5V and delivers an adjustable output voltage from 0.6V to VIN, with an output current capability of up to 1A.
The TPS62A01 integrates high-side and low-side MOSFET switches, providing synchronous rectification for improved power conversion efficiency. Operating at a fixed switching frequency of 2.4MHz, it enables the use of compact external inductors and capacitors, helping reduce overall power supply solution size.
The device automatically switches between pulse-width modulation (PWM) mode and power-save mode (PSM) according to load conditions. This operating mode helps maintain high efficiency across a wide load range while reducing power consumption during light-load operation.
With a quiescent current of less than 23µA and 1% feedback accuracy over the 0°C to +125°C temperature range, the TPS62A01 is suitable for battery-powered devices and other applications requiring efficient voltage regulation.
The converter features an integrated soft-start circuit to limit inrush current during startup. Additional protection and control functions include overcurrent protection, short-circuit protection with hiccup operation, thermal shutdown, active output discharge, and a power-good output signal.
The TPS62A01DRLR comes in a compact 6-pin SOT-563 (DRL / SOT-5X3) surface-mount package. Its small footprint makes it suitable for space-constrained PCB layouts and automated SMT manufacturing. The device operates over a junction temperature range of -40°C to +125°C.
Supplied in tape-and-reel packaging with a standard quantity of 4,000 pieces per reel, the TPS62A01DRLR supports automated pick-and-place assembly and high-volume electronic manufacturing.
