FSEZ1016A — Primary-Side-Regulation PWM Integrated Power MOSFET January 2010 FSEZ1016A Primary-Side-Regulation PWM Integrated Power MOSFET Features Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry Accurate Constant Current Achieved by Fairchild’s Proprietary TRUECURRENT™ Technique Green Mode: Frequency Reduction at Light-Load Fixed PWM Frequency at 43kHz with Frequency Hopping to Reduce EMI Low Startup Current: 10μA Maximum Low Operating Current: 3.5mA Peak-Current-Mode Control in CV Mode Cycle-by-Cycle Current Limiting Over-Temperature Protection (OTP) with Auto-Restart Brownout Protection with Auto-Restart VDD Over-Voltage Protection (OVP) with Auto-Restart VDD Under-Voltage Lockout (UVLO) SOIC-7 Package Description This primary-side PWM integrated power MOSFET significantly simplifies power supply designs that require CV and CC regulation capabilities. FSEZ1016A controls the output voltage and current precisely with only the information in the primary side of the power supply, not only removing the output current sensing loss, but also eliminating all secondary feedback circuitry. The green-mode function with a low startup current (10µA) maximizes the light-load efficiency so the power supply can meet stringent standby power regulations. Compared with conventional secondary-side regulation approach; the FSEZ1016A can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. FSEZ1016A is available in a 7-pin SOIC package. A typical output CV/CC characteristic envelope is shown in Figure 1.
