Primary Side Regulation PWM Integrated Power MOSFET
FSEZ1216 — Primary-Side-Regulation PWM Integrated Power MOSFET April 2009 FSEZ1216 — Primary-Side-Regulation PWM Integrated Power MOSFET Features Description The primary-side PWM integrated Power MOSFET, Constant-Voltage (CV) and Constant-Current (CC) FSEZ1216, significantly simplifies power supply design Control without Secondary-Feedback Circuitry that requires CV and CC regulation capabilities. Green Mode: Frequency Reduction at Light-Load FSEZ1216 controls the output voltage and current precisely only with the information in the primary side of Fixed PWM Frequency at 42kHz with Frequency the power supply, not only removing the output current Hopping to Reduce EMI sensing loss, but also eliminating all secondary Cable Voltage Drop Compensation in CV Mode feedback circuitry. Low Startup Current: 10μA The green-mode function with a low startup current (10µA) maximizes the light load efficiency so the power Low Operating Current: 3.5mA supply can meet stringent standby power regulations. Peak-Current-Mode Control in CV Mode Compared with conventional secondary side regulation Cycle-by-Cycle Current Limiting approach, the FSEZ1216 can reduce total cost, component count, size, and weight, while V Over-Voltage Protection with Auto-Restart DD simultaneously increasing efficiency, productivity, and V Under-Voltage Lockout (UVLO) DD system reliability. Gate Output Maximum Voltage Clamped at 18V A typical output CV/CC characteristic envelope is shown in Figure 1.
