LA5635H
Overview
The LA5635H power supply IC provides a set of functions optimal for car audio applications. These functions include
regulators, emitter-follower outputs, open-collector outputs, and a reset function.
Functions
5V/50mA regulator (always on, with reverse current flow prevention function)
10V, 2000mA regulator (when used with an external 2SB921 pnp transistor) with standby function (on/off control)
Regulators (four 8V systems and two 5V systems) with on/off functions controlled by a shift register/latch function.
This IC also provides four open-collector output systems and two emitter-follower type output systems.
Full complement of built-in protection circuits.
- Over current protection for each VO except the open-collector outputs.
- Thermal protection for each VO except the VDD 5V output.
Two reset circuit systems.
