Original spot RP504K121D-E2 step-down DC/DC converter

RP504K121D-E2: Step-Down DC/DC Converter. The company has inventory.

The RP504x is a low supply current, CMOS based PWM/VFM step-down DC/DC converter with synchronization

The rectifier has an output current of 600 mA *_1. Internally, a single converter consists of one oscillator, one reference

Voltage Unit, Error Amplifier, Switch Control Circuit, Mode Control Circuit (RP504xxx1A/D), Soft Start

circuits, latch-type protection circuits, under-voltage lockout (UVLO) circuits and switching transistors.

The RP504x adopts synchronous rectification, and the rectification efficiency is improved by replacement

Diodes with built-in switching transistors. Using synchronous rectification not only improves circuit performance

It also allows the design to reduce the number of parts.

Power control method can be selected from forced PWM control type or PWM/VFM automatic switching control

Input by inputting a signal to the MODE pin. Forces PWM control to switch at fixed frequency at low output current

Reduce noise. Likewise, at low output currents, PWM/VFM switches control automatically

Switch from PWM mode to VFM mode for high efficiency.

The output voltage is an internally fixed type, allowing output voltages from 0.8 V to 3.3 V in 0.1 V steps.

Output voltage accuracy is as high as ±1.5% or ±18 mV.

The protection circuits included in the RP504x are overcurrent protection circuits and latch-type protection circuits.

Overcurrent protection circuitry monitors inductor peak current during each switching cycle, and

If the LX current limit (ILXLIM) is exceeded, it will turn off the P channel Tr. Latch-type protection circuit latches the built-in driver

If the overcurrent condition persists, or enters the step-down state and stops the operation of the step-down DC/DC converter, or

VOUT continues to be at half the set voltage for a duration equal to or longer than the protection delay time (tprot). Cancel

Latch protection circuit, use CE pin to select standby mode or active mode, or power down

The supply voltage is below the UVLO detector threshold.

The RP504x is available in 6-pin DFN (PLP) 1216-6F, 6-pin DFN1616-6B and 5-pin SOT-23-5 packages

Achieve the smallest footprint solution on area-constrained boards.
