SP6837 controller equivalent, low-power off-line primary side regulation controller.
* Primary Side Control for Eliminating Opto-
coupler and Secondary CV/CC Control Circuitry
* 3.
The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supp.
The SP6837 has the built-in programmable cable voltage drop compensation function, which make it flexible to accommodate various cables with different gauges and lengths.
The SP6837provides accurate constant voltage, constant current (CV/CC) regulati.
