Featuring an integrated 725 V MOSFET, synchronous rectification and precise secondary-side feedback sensing control, the new IC family delivers excellent multi-output cross-regulation with full line protection and instantaneous transient response with less than 10 mW no load consumption.
MPM01 and MPM04 have a large output current of 3.0 A and generate large amounts of heat. Therefore, these modules are available as full mold packages that feature high heat resistance and a high-efficiency synchronous rectification circuit scheme.
Himalaya buck converters enable synchronous rectification over a wide input range from 4.5V min to 36V, 42V, 60V or 76V max, supporting output currents from 25mA to 5A with internal MOSFETs.
However, in a simple combination with synchronous rectification, normal control is no longer possible in continuous-mode operation, and there is the possibility that the primary-side switching elements(MOSFETs) and secondary-side rectification elements(MOSFETs) may be turned on simultaneously, so that a through-current gives rise to element destruction.
Features: Works for 85-484 V AC input Integrated line OV protection makes device safe for up to 650 V AC input Built-in synchronous rectification for higher efficiency Excellent cross-regulation using SR MOSFET instead of diode Primary sensed output overvoltage protection(OVP), eliminating the opto-coupler for fault protection To download DER-541 and learn more about InnoSwitch-EP 900V, visit the InnoSwitch-EP product page.
