R1215D Series PWM Step-up DC/DC Controller NO.EA-134-180705 OUTLINE The R1215D is a CMOS-based PWM step-up DC/DC controller with low supply current. The R1215D consists of an oscillator, a PWM comparator circuit, a reference voltage unit, an error amplifier, a reference current unit, a protection circuit, and an under voltage lockout (UVLO) circuit. A low ripple, high efficiency step-up DC/DC converter can be composed of this IC with some external components, or an inductor, a diode, a power MOSFET, resisters, and capacitors. The maximum duty cycle and the soft start time are easily adjustable with external resistors and capacitors.
