Describe
The RLCP2510 is a constant frequency, current mode step-down converter. The device integrates a main
switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for
powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The output voltage can
be regulated as low as 0.6V. The RLCP2510 can also run at 100% duty cycle for low dropout operation,
extending battery life in portable system. This device offers two operation modes, PWM control and PFM
Mode switching control, which allows a high efficiency over the wider range of the load. The RLCP2510 is
offered in a low profile 5-pin, SOT23-5 package, and is available in an Adjustable version.
