R1210Nxx2x SERIES PWM Step-up DC/DC Controller NO.EA-064-111123 OUTLINE The R1210Nxx2C/xx2D Series are CMOS-based PWM step-up DC/DC Converter controllers, with high accuracy, low supply current. Each of the R1210Nxx2x Series consists of an oscillator, a PWM circuit, a reference voltage unit, an error amplifier, phase compensation circuit, resistors for voltage detection, a chip enable circuit, a controller against drastic load transient and an output voltage detector. A low ripple, high efficiency step-up DC/DC converter can be composed of this IC with only four external components, or an inductor, a diode, a transistor and a capacitor. The R1210Nxx2x Series can detect drastic change of output voltage with a circuit controller, the load transient response is improved.
