VIPer53 is a switch power supply control IC from ON Semiconductor. It features an enhanced current mode PWM controller and a high voltage MDMesh power MOSFET in a single package. It can provide up to 30W of secondary power for various switch power supplies, and has overload and short circuit protection functions.
The ViPer53 family combines an enhanced current‑mode PWM controller with a high‑voltage PowerSO‑10 MOSFET in a single package. It is intended for offline power supplies, offering up to 30 W (DIP‑8) or 65 W (PowerSO‑10) output power and features such as soft‑start, automatic burst mode, and comprehensive protection functions.
Key specifications include a switching frequency up to 300 kHz, current limitation with adjustable thresholds, over‑temperature and over‑voltage lockout, and a DIP‑8 or PowerSO‑10 package with defined thermal resistances. The document details pin assignments, absolute maximum ratings, and detailed electrical characteristics for design engineers.
| Switching Frequency | up to 300 kHz |
|---|---|
| Continuous Drain Current (Ip) | Internally limited |
| Supply Voltage (Vop) | 0 … 19 V |
Vppon is typically 11.5 V, and Vppo# (the stop‑switching threshold) is typically 8.4 V.
The device provides overload and short‑circuit control, over‑temperature protection, over‑voltage lockout with hysteresis, soft‑start/shutdown, and automatic burst mode in standby.
