Sanyo LA4630N Specifications

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Monolithic Linear IC

9V/12V 3-Dimension Power IC for

Radio Cassette Recorders

Ordering number:ENN3227A

LA4630N

SANYO Electric Co.,Ltd. Semiconductor Company

TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN

Features

• Stereo section 9V/3Ω 3W×2, 12V/3Ω 5W×2 : noise filter

capacitorless power.

• Super bus section 9V/3Ω 6W, 12V/3Ω 10W : output ca-

pacitor, B-S capacitorless power.
This chip employs technology for eliminating pins and
external connections to realize 3-dimensional power on a
single chip. This IC is a single package power IC for
making sound systems with punch.

• On-chip pop noise suppressor.

• On-chip power switch circuit.

• External and mute functions on chip.

• Protection functions on chip (thermal protection circuit
and BTL section RL short protection circuit)

For power supply transistor regulation, the equivalent power line resistance is 3Ω or greater.

[Precaution concerning the metal]

Select PO with a goal of a rated load/rated supply voltage of RL=3 to 8Ω and VCC=5 to 18V and design to avoid
exceeding the package Pd max of 37.5W. For heavy loads or high VCC, the drive design is involved and the power
effect deteriotates, so pay attention to these factors.

Block Diagram

Note 1 : The motor should not be connected to the power switch pin, since transient noise may appear on the amplifier

outputs when the motor is started or stopped.

Note 2 : Audio mute is enabled by connecting a 300Ω resistance between the DC pin and ground. DC bias control of

both the stereo (L ch, R ch) and BTL (super bass) channels is enabled, and all audio output signals can be
muted by controlling the MUTE pin.
