TDA21462

The TDA21462 power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged with Schottky diode, and high-side and low-side MOSFETs. The TDA21462 power stage forms a complete low voltage, high power DC/DC regulator when used with Infineon multiphase controller ICs. The TDA21462 internal MOSFET current sense algorithm with temperature compensation achieves superior current sense accuracy versus best-in-class controller-based inductor DCR sense methods. Operation at switching frequency as high as 1.5 MHz enables high performance transient response, allowing reduction of output inductance and output capacitance while maintaining industry leading efficiency.
