R1210Nxx1x SERIES PWM STEP-UP DC/DC CONVERTER NO.EA-075-170303 OUTLINE The R1210Nxx1x Series are CMOS-based PWM step-up DC/DC Converter, with high accuracy, low supply current. Each of the R1210Nxx1x 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. Further, includes a controller against drastic load transient, a control transistor with low ON-Resistance, ‘LX switch’, and a protection circuit for LX switch and an output voltage detector. R1210Nxx1A Series contain further a circuit for changeover oscillator frequency each.
