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 o...
