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 (Ni MH) batteries, or a single Li+ battery. This IC consists of a reference voltage unit with soft start, error amplifiers, PWM parator, 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 posed of RP600K series with only an inductor, a diode, divider resistors and capacitors. In terms of output voltage setting, fixed type and adjustable with external divider resisters type are available. Output voltage is from 2.3V to 5.5V.
The built-in LDO Regulator(VR) consists of a reference voltage unit, an error amplifier, output...
