Off-line, non-inductive AC input linear regulator ZCC2786
. 1, Product Description:
ZCC2786 is a compact non-linear regulator off-line inductor design. ZCC2786 may provide two output voltages, wherein the output voltage VOUT set by the internal 5V / 3.3V / 2.7V three versions, and can provide a set of output VOUT1 voltage of 0.66 × VOUT. ZCC2786 is a simple and reliable solution to obtain off-bias power supply. ZCC2786 integrates a 650V power MOSFET, a start control circuit, the VDD voltage control circuit, the AC signal AC synchronous detection circuit, low dropout regulator and the like. The chip energy input AC via the intelligent control system to reduce losses, improve system efficiency and reduce system standby. ZCC2786 fully integrated with self-recovery protection function: VDD undervoltage protection, VDD over voltage protection, output overload protection, output undervoltage protection, lightning surge protection and built-in over-temperature protection.
