VIPer50A-E/ASP-E is a single-chip switch power supply controller from ST. It uses VIPower M0 technology and integrates high voltage MOSFET and PWM circuit, with adjustable switching frequency, soft start and shutdown control, automatic burst mode operation, low standby current, adjustable current limitation and other features. It is suitable for 25W wide range or single range output power supply or switch power supply with doubler configuration.
The VIPer50A‑E and VIPer50ASP‑E are high‑voltage, current‑mode SMPS controller ICs that integrate a trimmed Zener reference, a vertical power MOSFET and a PWM circuit on a single silicon chip. They are designed for offline power‑supply applications requiring up to 700 V drain‑source voltage, low standby current and burst‑mode operation.
