DC/DC Converter Secondary Side Control IC
LA5636M
Monolithic Linear IC
52303AS (II) No.7258-1/7
Overview
The LA5636M is a DC/DC Converter Secondary Side
Control IC that draws power from a car battery and is ideal
for use in rechargers for lithium ion batteries, etc. Because
this IC incorporates only the basic functions (constant
voltage control and constant current control) that are
needed in an IC for charging, it can be easily used in
combination with other ICs for charging.
Features
Includes integrated circuitry for preventing the
malfunction of the system in the event that the input
voltage (car battery voltage) drops.
Produces constant voltage output in proportion to the
PWM input signal. (Permits output voltage control by
microcontroller.)
High-precision reference current (current control amp):
92.5
A±2.7%
Output voltage can be set through an external resistor.
Each loop of the voltage amp and current amp is
independent.
