TPS40040 Datasheet (Texas Instruments) - SYNCHRONOUS BUCK DC-TO-DC CONTROLLER

TPS40040, SYNCHRONOUS BUCK DC-TO-DC CONTROLLER

The TPS40040 and TPS40041 dc-to-dc controllers are designed to operate from a 2.25-V to 5.5-V input source.

To reduce the number of external components, several operating parameters are fixed internally; namely, frequency, soft start time, and short circuit protection (SCP) levels.

For example, the
