LA5657H Description
Monolithic Digital IC LA5657H System Power Supply IC for Car AV Systems Overview The LA5657H provides 10 V/2.2 A and 5 V/1.4 A external pnp transistor based low-saturation regulators with standby functions, as well as 3.3 V, 5 V, and 8 V constant voltage, open collector, and VCC linked (VCC 1 V) outputs that can be controlled from serial data (CCB). It also includes three reset detection circuits for the VDD, ACC,...
