Description
The R1224N Series is a family of CMOS-based PWM step-down DC/DC Converter controllers that need little supply current. These IC chips consist of various circuits, including oscillators, a soft-start circuit, resistors for detecting the output voltage, and input voltage detection circuit. The R1224N Series is capable of low ripple, high efficiency, step-down DC/DC conversion with few external components. The output voltage is either fixed or adjustable with external resistors, without the PWM/VFM alternative circuit.
