R1211D103C, R1211N002A, STEP-UP DC/DC CONTROLLER
R1211x SERIES STEP-UP DC/DC CONTROLLER NO.EA-088-0604 OUTLINE The R1211x Series are CMOS-based PWM step-up DC/DC converter controllers with low supply current.
Each of the R1211x Series consists of an oscillator, a PWM control 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 indu
