RP400xxx1C SERIES
HIGH EFFICIENCY, SMALL PACKAGES, STEP-UP DC/DC CONVERTERS
NO.EA-193-100317
OUTLINE
RP400xxx1C Series are high efficiency, step-up DC/DC converter ICs packaged in compact 5pin SOT23 or 6pin
DFN (PLP). This converter starts up of low voltage (Typ.1.2V) operation from two alkaline or a single Li+ battery.
This IC consists of a reference voltage unit with soft start, error amplifier, PWM comparator, current limit circuit
and internal switch and PWM/VFM mode control circuit. A low ripple high efficiency step up DC/DC converter can
be composed of RP400xxx1C Series with only an inductor, a diode, divider resistors and a capacitor. This
converter is based on a fixed frequency current mode PWM control which goes to power save mode (VFM mode)
at light load automatically. RP400xxx1C Series has built-in Anti-ringing Switch to prevent switching node from
ringing, when the converter enters the discontinuous current mode.
The output voltage of RP400K001C can be set within 1.8~5.0V (recommended range of output voltage) by
external divider resistors.
