TPS562202S ECO Mode Synchronous Buck Converter
Author: EIS Release Date: Feb 9, 2021
Texas Instruments' 4.3 V to 17 V input, 2 A converter maintains high efficiency during light-load operation
Texas Instruments' TPS562202S is a simple, easy-to-use, 2 A synchronous buck converter in a SOT563 package. The device is optimized to operate with minimum external components and optimized to achieve low-standby current. This switch-mode power supply (SMPS) device employs D-CAP2 mode control providing a fast transient response and supporting low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. The TPS562202S operates in ECO mode, which maintains high efficiency during light-load operation. The TPS562202S is available in a 6-pin 1.6 mm × 1.6 mm SOT563 (DRL) package and specified from a junction temperature range of -40°C to +125°C.
