The TPS565208 is a simple, easy-to-use, 5-A synchronous step-down converter in SOT-23 package.
The device is optimized to operate with minimum external component count and also optimized to achieve low standby current.
This switch mode power supply (SMPS) device employs D-CAP2™ mode control, which provides fast transient response and requires no external compensation components. D-CAP2™ also allows the use of low-equivalent series resistance (ESR) specialty polymer capacitors and ceramic capacitors.
The TPS565208 is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, and operates over a –40°C to 125°C junction temperature range.
