RP519Z Series

0.5A/1A PWM/VFM Step-down DC/DC Converter with Synchronous Rectifier

NO.EA-419-180711

OUTLINE

The RP519Z is a low supply current CMOS-based PWM/VFM step-down DC/DC converter with synchronous

rectifier featuring 0.5 A / 1 A output current

(1)

. Internally, a single converter consists of a reference voltage unit,

an error amplifier, a switching control circuit, a mode control circuit, a soft-start circuit, an under-voltage lockout

(UVLO) circuit, a thermal shutdown circuit, and switching transistors. The RP519Z is employing synchronous

rectification for improving the efficiency of rectification by replacing diodes with built-in switching transistors.

Using synchronous rectification not only increases circuit performance but also allows a design to reduce parts

count. Output voltage controlling method is selectable between a forced PWM control type and a PWM/VFM

auto-switching control type, and can be set by the MODE pin. Output voltage type is selectable between an

internally fixed output voltage type and an externally adjustable output voltage type. Protection circuits in the

RP519Z is current limit circuit and thermal shutdown circuit. LX current limit value (Typ.) is selectable between

1.6 A and 1.0 A.

The RP519Z is available in WLCSP−6−P8 which achieves high-density mounting on boards. Using capacitor

of 0402- / 1005-size (inch / mm) and inductor of 0603- /1608-size (inch / mm) as external parts help to save

space for devices.
