LA4601N
Overview
The LA4601N is a modified package version of the LA4600 power IC that requires an extremely small number of external
components. While its main specifications are for use in VCC = 15V systems, it can be used without a heat sink in VCC =
9V systems. The design of the LA4601N obviates the need for external BS and NF capacitors and an oscillation prevention
RC circuit, since these functions are integrated in the device itself.
Functions
Pin compatibility with the LA4600.
No heat sink required when used at 9V.
Output power at VCC = 15V, 3Ω load: 7.0W×2.
Built-in standby switch.
Built-in thermal protection circuit.
