7.5W Automotive SEPIC Reference Design (PMP8671)

The PMP8671 is a single-ended primary-inductor converter ( SEPIC) reference design based on an automotive quality controller IC - the TPS40210-Q1. It operates over a 4.5-V to 24-V input range and delivers 6.25 Vat 1.2-A maximum output current. The switching frequency is set to 400 kHz to provide excellent load and line regulation, while maintaining good phase and gain margin. Designed for automotive applications, this reference design operates with cold cranking down to 3 V.


Low-cost SEPIC Excellent load and line regulation Built on a universal board -for reducing EMI, a layout proposal is provided
