Description

The R1244N001B-TR-FE Series are 30V input, CMOS-based PWM step-down DC/DC converters featuring 1.2A∗ output current. R1240x/R1244N include a soft start circuit and a latch or a fold-back protection circuit. By simply using an inductor, resistors, a diode, and capacitors as external components, a high-efficiency step-down DC/DC converter can be easily configured. Due to current mode PWM control, the R1240x/R1244N provide a fast response and high efficiency.

Applications:

1. Power source for digital home appliances such as digital TVs and DVD players

2. Power source for office automation equipment such as printers and fax machines
