Product Description

HM2786 is an off-line linear regulator with a compact non-inductor design. HM2786 can provide two sets of outputs The VOUT output voltage has been internally set to 5V/3.3V/2.7V. At the same time, VOUT1 A set of 0.66×VOUT output voltage can be provided. HM2786 is a simple and reliable way to obtain bias power supply Offline power solution.

HM2786 integrates 650V power MOSFET, start control circuit, VDD voltage control circuit, AC signal No. synchronous detection circuit, low dropout voltage regulator, etc. The chip intelligently controls the AC energy input to reduce the system System loss, improve system efficiency, and effectively reduce system standby at the same time. HM2786 integrates complete protection functions with self-recovery function: VDD under-voltage protection, VDD over-voltage protection, Output overload protection, output undervoltage protection, lightning surge protection and built-in over-temperature protection, etc.
