The FSEZ1216B is a PWM integrated power MOSFET from Fairchild Semiconductor Corporation that features CV and CC control, low startup current, low operating current, peak current mode control, cycle-by-cycle current limiting, VDD over-voltage protection, VDD under-voltage lockout, fixed over-temperature protection, and is available in a DIP-8 package. It is best suited for battery charger applications for cellular phones, cordless phones, PDAs, digital cameras, and power tools.
The FSEZ1216B is a highly integrated PWM controller designed to enhance the performance of low-power flyback converters. It features proprietary topology that simplifies circuit design, particularly for battery charger applications, by eliminating the need for secondary feedback circuitry. The device includes Constant-Voltage (CV) and Constant-Current (CC) control modes.
| Operating Junction Temperature (Tj) | +150 °C |
|---|---|
| Storage Temperature Range | -55 to +150 °C |
| Drain-Source Voltage (VDS) | 600 V |
| Maximum Duty Cycle | 75 % |
The startup current is only 10uA, which allows for large startup resistance to save power.
The device is available in an 8-pin DIP package.
No, it provides Constant-Voltage and Constant-Current control without secondary-feedback circuitry.
