STMicroelectronics STACF01B
The STACF01B is intended for use with DC input, like SMPS with PFC in front or supplied by a DC bus. The ICs incorporate two low-side low-power drivers intended to drive the inputs of an external high-voltage half-bridge driver ICs or an SiP such as one of the MasterGaN families. It also provides an extensive set of protection features against primary and secondary side faults (two-level overcurrent, overpower, overload, short circuit, brownout, output overvoltage).| Part No. | STACF01B |
