RP502x SERIES

Step-down DC/DC Converter with Synchronous Rectifier

NO.EA-189-160706

OUTLINE

The RP502x Series are CMOS-based step-down DC/DC converters with synchronous rectifier.

Each of these ICs consists of an oscillator, a reference voltage unit, an error amplifier, a switching control

circuit, a soft-start circuit, protection circuits, an UVLO circuit, and switching transistors. By adopting the

synchronous rectification with built-in switching transistors, high efficient step-down DC/DC converter can be

composed of only an inductor and capacitors.

As protection circuits, the current limit circuit and the latch protection circuit are built into the ICs. The current

limit circuit controls the peak current of L

at each clock cycle. Latch protection circuit maintains the built-in driver

in OFF state if the load current exceeds the limit value for a certain period of time. To cancel the latch protection,

disable the ICs with a chip enable circuit and then enable it again or make the power supply voltage lower than

UVLO.

The setting voltage for the RP502x Series is the output voltage fixed type with built-in feedback resistance that

is adjustable in 0.1V step with the accuracy of ± 1.5% or ±24mV. The packages for the ICs are WLCSP-6-P2

and DFN1616-6, which enable the high-density mounting. The switching mode for the ICs is selectable from the

PWM/VFM auto switching type, which achieves the high efficiency at the light load condition or PWM fixed type,

which switches at the fixed frequency.
