The AP8012HSEC-R1 with Switching Controllers SOP-8 RoHS is a single-stage switch-mode pulse-width modulation (PWM) circuit, designed for off-line and DC-to-DC converter applications. It features internal switching regulators that operate at high frequency to provide a board-level solution with an adjustable output voltage. It features an internal 650V startup switch, which helps to minimize the external components needed for the design. The AP8012HSEC-R1 also features undervoltage lockout, overcurrent protection, and thermal shutdown for increased reliability and safety of the design. This product is highly efficient and RoHS compliant, and is manufactured by Chipown.
