UC1875J883B

The UC1875 family of integrated circuits implements control of a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other, allowing constant frequency pulse-width modulation in combination with resonant, zero-voltage switching for high efficiency performance at high frequencies.This family of circuits may be configured to provide control in either voltage or current mode operation, with a separate over-current shutdown for fast fault protection.The UC1875J883B belongs to UC1875 family.

The absolute maximum ratings of the UC1875J883B can be summarized as:(1):the supply voltage is 20V;(2):the output current,DC is 0.5A;(3):the output current,pulse(0.5s) is 3A;(4):the analog I/0s is -0.3V to 5.3V;(5):the storage temperature range is -65 to +150;(6):the junction temperature is 55 to +150;(13):the lead temperature (soldering,10 seconds) is +300.Pin references are to 20 pin packages.All voltages are with respect to ground. currents are positive into,negative out of,device terminals.consult unitrode databook for information regarding thermal specifications and limitations of packages.
