Средства разработки интегральных схем (ИС) управления питанием MAX17690EVKITA#

Обратноходовой контроллер без оптоизоляции , режим прерывистой проводимости, режим пикового тока, 60В

The MAX17690EVKITA# is an evaluation kit for evaluating MAX17690 no-opto flyback with secondary side synchronous rectification. It is a fully assembled and tested circuit board that demonstrates the operation of an isolated MAX17690 DC to DC converter. This circuit is implemented using MAX17690, a no-opto, flyback controller in a 16 pin TQFN package with an exposed pad. The synchronous rectification on secondary side is enabled by replacing the secondary diode with a MOSFET to achieve 90% efficiency. The circuit uses MAX17606, a secondary side synchronous rectifier driver in 6 pin SOT-23 package for driving secondary side MOSFET. The EV kit output is configured for an isolated +5V and provides up to 1A of output current. The transformer provides galvanic isolation between input and output up to 1875Vrms. It regulates output voltage within ±5% over the line, load and temperature without using auxiliary winding/optocoupler for output voltage feedback.

• Input voltage range from 18V to 36V
• Compact design with high frequency (150KHz) switching
• No optocoupler
• third winding required to derive feedback signal
• Proven PCB layout
