RP600K SERIES
Step-Up DC_DC Converter with voltage regulator and detector
NO.EA-237-160330
OUTLINE
RP600K series are high efficiency, current mode step-up DC-DC converter ICs with a voltage regulator and a voltage detector. This converter starts up of low voltage (typ. 0.8V) operation from one or two alkaline or nickel-metal-hydride (NiMH) batteries, or a single Li+ battery. This IC consists of a reference voltage unit with soft start, error amplifiers, PWM comparator, protection circuits such as a current limit circuit, an internal switch transistor, an oscillator, and PWM/VFM mode control circuit. A low ripple high efficiency step-up DC/DC converter can be composed of RP600K series with only an inductor, a diode, divider resistors and capacitors.
