SP6837
LOW-POWER OFF-LINE PRIMARY SIDE REGULATION CONTROLLER
DESCRIPTION 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) regulation without requiring an opto-coupler and secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining stability.
The SP6837 achieves excellent regulation and high average efficiency, yet meets the requirement for no-load consumption less than 30mW.
The SP6837is a high performance AC/DC power supply controller for battery charger and adapter applications. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.
The SP6837is available in SOIC-8 package.
