Description
The R1211D002A-TR is a CMOS-based PWM step-up DC/DC converter controller with low supply current. It 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. With the addition of some external components, such as an inductor, a diode, a power MOSFET, divider resistors, and capacitors, this IC can be used to create a low ripple and high efficiency step-up DC/DC converter.
