Средства разработки интегральных схем (ИС) управления питанием MAXREFDES115C#

Эталонная плата , изолированный источник питания 24В до 5В 20Вт

The MAXREFDES115C# is a compact, isolated 24V to 5V, 20W power supply reference design. It is an efficient active clamp topology design with 24V input and 5V at 4A (20W) of power. The board demonstrates the application of MAX17599 low IQ, wide input range, active clamp current mode PWM controller. The reference design features active clamp transformer reset topology for forward converters. This reset topology has several advantages including reduced voltage stress on the switches, transformer size reduction due to larger allowable flux swing and improved efficiency due to elimination of dissipative snubber circuitry. These features result in a compact and cost effective isolated power supply. In addition, through hole pins on the bottom side of the module allow quick and easy integration of this power converter into any system. Pins are 15.24mm from power to ground and 63.5mm from the input side to the output side. It is typically used in PLCs, telecom and Datacom power supplies.
