CoolSET™-F3 is an offline switch mode power supply (SMPS) current mode controller with integrated 650V startup cell and CoolMOS™ technology. It offers high performance and reliability.
The CoolSET‑F3 is an off‑line SMPS current‑mode controller featuring a 650 V avalanche‑rated CoolMOS™ device with an integrated switchable startup cell. It supports active‑burst mode to achieve standby power below 100 mW and includes multiple protection functions such as Auto‑Restart for over‑voltage, overload, open‑loop and undervoltage conditions.
The device is offered in several package types (PG‑DIP‑8‑6, PG‑DIP‑7‑1, P‑TO220‑6‑46/47) with fixed switching frequencies of 67 kHz or 100 kHz, a maximum duty cycle of 72 % and a current‑limiting tolerance of less than ±5 %. Ordering codes and detailed electrical characteristics are provided for each variant.
| Voltage rating | 650 V |
|---|---|
| Standby power (active‑burst) | < 100 mW |
| Switching frequency | 67 kHz / 100 kHz (fixed) |
| Maximum duty cycle | 72 % |
| Current‑limiting tolerance | < ±5 % |
| Protection mode | Auto Restart (over‑voltage, overload, open‑loop, undervoltage) |
| Package types | PG‑DIP‑8‑6, PG‑DIP‑7‑1, P‑TO220‑6‑46, P‑TO220‑6‑47 |
The device achieves standby power below 100 mW in active‑burst mode with no load.
It provides Auto Restart Mode for over‑voltage detection, overload, open‑loop, and VCC undervoltage conditions.
The controller operates at a fixed switching frequency of either 67 kHz or 100 kHz, depending on the package.
