Revision No : 0

The FTD1601 is a series of easy to use fixed and adjustable

step-down(buck) switch-mode voltage regulators. These

devices are available in fixed output voltage of 5V, and an

adjustable output version. Both versions are capable of driving a

3A load with excellent line and load regula�on.

Requiring a minimum number of external components, these

regulators are simple to use and include internal frequency

compensa�on, and a fixed-frequency oscillator.

The output voltage is guaranteed to ±3% tolerance under

specified input voltage and output load condi�ons. The

oscillator frequency is guaranteed to ±15%. External shutdown

is included, featuring typically 80 µA standby current. Self

protec�on features include a two stage frequency reducing

current limit for the output switch and an over temperature

shutdown for complete protec�on under fault condi�ons.

The FTD1601 is available in TO-263-5L packages.
