Overview
Package Dimensions
The LA4636 is a BTL power IC that is pin-compatible
unit: mm
with the LA4635A and LA4635B single-end power ICs. It
represents a new concept in devices of this type by
allowing design editing based on common circuit board pin
3049B-SIP12H

Set VCC, RL, and output level such that Pd max. is not exceeded for the size of heat sink used.
*1: Assuming two-channel output with an I_O peak per channel exceeding 1.0 A. If the I_O peak per channel is 1.0 A or
less, the allowable operating voltage range is 5.5 to 20 V (range not exceeding Pd max.) for all R_L values.
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.
