Product details

500 mA output with 300 kHz switching

The TPS62100DR: This is a single-output step-down (buck) regulator delivering up to 500 mA. The 300 kHz switching frequency is moderate — it keeps inductor size reasonable without pushing switching losses too high.

Industrial temperature grade and synchronous rectification

The built-in synchronous rectifier improves efficiency at lower output voltages by replacing the freewheeling diode with a low-Rds(on) FET.

Input range and package

Input voltage range is 2.5 V to 9 V.
