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 µA±2.7%
• Output voltage can be set through an external resistor.
• Each loop of the voltage amp and current amp is independent.
