Texas Instruments TPS562202 | Demoboard TPS562202EVM
4.3-V to 17-V input, 2-A output, synchronous step-down voltage converter
Overview
| Topology | Buck Converter |
| Input voltage | 4.3-17 V |
| Output 1 | 1.05 V / 2 A |
Description
The TPS562202 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 also 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 both low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.The TPS562202 operates in ECO mode, which maintains high efficiency during light load operation. The TPS562202 is available in a 6-pin 1.6-mm × 1.6-mm SOT563 (DRL) package, and specified from a –40°C to 125°C junction temperature.
