LP3773 Product Details

description

LP3773/4/5 is a high performance AC/DC power controller for battery chargers and adapters with built-in VCBO

750V power transistor. The device uses pulse frequency modulation (PFM) to establish discontinuous conduction mode (DCM)
Flyback power supply.
LP3773/4/5 provides precise constant voltage, constant current (CV / CC) does not require optocoupler and secondary control circuit
Adjustment. It also eliminates the need for loop compensation circuitry while maintaining good stability. LP3773/4/5 can achieve good
The regulation and higher average efficiency satisfy the no-load loss of less than 30mW.
LP3773/4/5 has a proprietary output cable voltage drop compensation function, that is, output line loss compensation, line loss compensation can be adjusted
The FB divider resistor is adjusted to adjust the maximum compensation amount to 12% of the output voltage, which can effectively compensate the output current at the output line.
Loss voltage drop on.
