Datasheet Specifications

Part number: FSEZ1317
Manufacturer: Fairchild Semiconductor
File Size: 1.17 MB
Datasheet: FSEZ1317_FairchildSemiconductor.pdf
Description: Primary-Side-Regulation PWM

Features

* Low Standby Power Under 30mW
* High-Voltage Startup
* Fewest External Component Counts
* Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
* Green-Mode: Linearly Decreasing PWM Frequency
* Fixed PWM Frequency at 50kHz with Frequenc

Applications

* A low-cost, smaller, and lighter charger results, as compared to a conventional design or a linear transformer. To minimize standby power consumption, the proprietary green mode provides off-time modulation to linearly decrease PWM frequency under light-load conditions. Green mode assists the power
