This reference design uses a TL2842B as a high-side buck to convert a 120-Vac input to a 24-Vdc output capable of 1-A loading. At full load, it acheives a low peak-to-peak output ripple and over 88% efficiency at full load. This reference design was built using a 2-layer PCB and single-sided assembly.
