R1224N502M-TR-FE - Brand New RICOH IC Chips
-
Description
The R1224N502M-TR-FE is a CMOS-based PWM step-down DC/DC Converter controller IC with low supply current. It consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a phase compensation circuit, a soft-start circuit, a protection circuit, a PWM/VFM alternative circuit, a chip enable circuit, resistors for output voltage detect, and input voltage detect circuit. This IC can easily compose a low ripple, high efficiency step-down DC/DC converter with only several external components, or a power-transistor, an inductor, a diode and capacitors. The output voltage is fixed or can be adjusted with external resistors (Adjustable types are without PWM/VFM alternative circuit).
