MAXREFDES120#, Isolated 24V to 5V, 12.5W No-Opto Flyback Power Supply Reference Design

MAXREFDES120#, Reference Design is an efficient no-opto flyback topology with 24V input and a 5V output at 12.5W of power (2.5A). The design features the MAX17690 (a peak-current-mode converter with flexible switching frequency) and the MAX17606 (a secondary side MOSFET driver for flyback converter). The combination of no opto-coupler and a secondary side MOSFET result in a design that is optimized for space, cost and efficiency. This entire circuit fits on a 20.3mm (0.8in) x 59.7mm (2.35in) board
