RP500x SERIES

600mA* Step-down DC/DC Converter with Synchronous Rectifier

NO.EA-155-090120

OUTLINE

The RP500x Series are CMOS-based 600mA* step-down DC/DC Converters with synchronous rectifier.

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

amplifier, a soft-start circuit, protection circuits, UVLO circuit, switching transistors, and so on. A low ripple, high

efficiency step-down DC/DC converter can be easily composed of this IC with only an inductor and capacitors.

In terms of the output voltage, since the feedback resistances are built-in, the voltage is fixed internally. 0.1V

step output can be set by laser-trim and 1.5% or 24mV tolerance depending on the output voltage is guaranteed.

Mode alternative circuit works automatically for improving the efficiency. Considering fixed noise frequency,

PWM fixed control type is also available.

As protection circuits, the current limit circuit which limits peak current of Lx at each clock cycle, and the latch

type protection circuit which works if the term of the over-current condition keeps on a certain time exist. The

latch-type protection circuit works to latch an internal driver with keeping it disable. To release the condition of

the protection, after disabling this IC with a chip enable circuit, enable it again, or restart this IC with power-on or

make the supply voltage at UVLO detector threshold level or lower than UVLO.

Since packages are WLCSP-6-P2, DFN(PLP)1820-6, SOT-23-6W, high density mounting on boards is

possible.

*)This is an approximate value, because output current depends on conditions and external parts.
