MP5493

36V, 0.6A, 550kHz, Synchronous

Buck Supercapacitor Charger and

Boost for PLC Mode

DESCRIPTION

FEATURES

The MP5493 is an energy backup and

management unit that provides a very compact

and efficient energy management solution for

the power line carrier (PLC) in power meters.

The MP5493 consists of a buck DC/DC

converter combined with a bidirectional DC/DC

•

Wide 5V to 36V Operating Input Voltage

(V_IN)

Real-Time Input Shutdown Detection to

Enable Boost Mode

Input Status Indicator

Buck Converter:

o 600mA Continuous Output Current (I_OUT

o 600mΩ/320mΩ Internal Power

MOSFETs

o Power-Save Mode for Light Loads

o Internal Soft Start (SS)

o Low-Dropout (LDO) Mode

o Short-Circuit Protection (SCP) with

Hiccup Mode

o Adjustable Output from 0.8V

Bidirectional Converter for Supercapacitor

Charger and Boost

charger and boost topology. The MP5493 uses

the bidirectional converter to achieve optimal

energy transfer and to provide the most cost-

effective energy storage solution.

The MP5493 achieves high power conversion

efficiency across a wide load range by scaling

down the switching frequency (f_SW) under light-

load conditions to reduce switching and gate

driving losses. Thermal shutdown provides

reliable and fault-tolerant operation.

The MP5493 is available in a cost-effective

TSOT23-8 package.
