8 s OUTLINE PWM/VFM step-down DC/DC converter with Synchronous Rectifier R1230D Series The R1230D Series are PWM step-down DC/DC Converters with synchronous rectifier, low supply current by CMOS process.
Each of these ICs consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, protection circuits, a protection against miss operation under low voltage (UVLO), PWM/VFM alternative circuit, a chip enable circuit, and a driver transistor.
A low ripple, high efficiency step-down DC/DC converter can be easily composed of this IC with only a few kinds of external components, or an inductor and capacitors.
