LP3783
Low Standby Power Off-Line PSR Driver
Description
The LP3783 is a high performance AC/DC power
supply controller for battery charger and adapter
applications which integrated 750V high voltage BJT.
The device uses Pulse Frequency Modulation (PFM)
method to build discontinuous conduction mode
(DCM) flyback power supplies.
The LP3783 provides accurate constant voltage,
constant current (CV/CC) regulation without requiring
opto-coupler and the secondary control circuitry. It
also eliminates the need of loop compensation
circuitry while maintaining good stability.
The LP3783 can achieve excellent regulation and
high average efficiency which is suitable for US DoE
VI requirement, yet meets no-load consumption less
than 75 mW.
The LP3783 provides many protections which
include OVP ,OTP and output short protection.
The LP3783 is available in SOP7.

Note 1: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Under “recommended operating
conditions” the device operation is assured, but some particular parameter may not be achieved. The electrical characteristics table defines the operation
range of the device, the electrical characteristics is assured on DC and AC voltage by test program. For the parameters without minimum and maximum
value in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec.
Note 2: The maximum power dissipation decrease if temperature rise, it is decided by TJMAX, θJA, and environment temperature (TA). The maximum power
dissipation is the lower one between PDMAX = (TJMAX - TA)/ θJA and the number listed in the maximum table.
