RP519 系列
0.5A/1A 6MHz带同步整流器功能的PWM/VFM降压DC/DC转换器

  • 概述

    The RP519 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.

    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 RP519 is current limit circuit and thermal shutdown circuit. LX current limit value (Typ.) is selectable between 1.6 A and 1.0 A.

    The RP519 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.

    *1: This is an approximate value. The output current is dependent on conditions and external components.
