    Products Detail

    An inductorless switching power supply demoboard that operates directly from 90-270VAC input. It provides two outputs: a main adjustable output (V_OUT) and a regulated 5.0V output (V_REG). The design uses a pass transistor and storage capacitor to achieve efficiency without magnetics. Features include enable control, adjustable output voltage (9.0V-50V), and meets conducted EMI requirements with modifications. Note: No galvanic isolation, dangerous voltages present.

    Key Features

    • Inductorless design, Dual outputs: adjustable V_OUT (12.6V nominal) and regulated 5.0V, Wide input range: 90-270VAC, Enable pin control, Adjustable output voltage (9.0V-50V), Efficiency up to 52%, Meets EMI requirements with modifications
