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.
A low ripple, high efficiency step-up DC...
