Monolithic Linear IC
LA5647H
Overview
For Car AV Equipment
Multifunction Multi-Voltage Power Supply
The LA5647H 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.
Features
* 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 for 8V systems and one 5V system) with on/off functions controlled by a shift resister/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. 1) Overcurrent protection for each VO except the open collector outputs. 2) Thermal protection for each VO except the VDD5V output.

Application examples Pin 1 : ACC5V, digital 5V Pin 11 : Insert a capacitor of about 10F between this pin and pin 12 to improve the TAPE8V ripple rejection. This pin controls the pin 12 output voltage. Set this pin to about 7V by inserting a resistor between this pin and ground if impulse noise from the Dolby IC occurs in cranking mode. Pin 12 : TAPE8V Pin 15 : 9 pro VCC as 9 RD 8V Pin 17 : FM8V power supply for use with a band switch Pin 18 : COM8V power supply for an electronic volume/tone control circuit. * : Note that total of Pd must not exceed the rating of the IC. 2 3 4 VCC CONT CN1 Pin 2 : Power supply * : This pin must be at the same voltage level as the emitter of the external transistor. Pin 3 : Bias for the external Transistor. The maximum sink current is 20mA. Pin 4 : Ripple rejection for each of the power supply systems. To increase the rejection capacity, insert a 1F capacitor between this pin and pin 27. This pin controls the COM10V output voltage. The voltage is set to 10V internally. 27 COM10V Pin 27 : The 10V power supply used for CD power, tuner VT, cassette loading, LCD, and ILL illumination. * Used as the power supply for internal 8V and 5V (except VDD5V) systems. * The output voltage can be controlled with the CN1 pin. * The ripple rejection can be improved at the CN1 pin.
