Description
The BP8519C is a high precision Non-isolated buck
switch for constant output voltage application. The
device is suitable for 85Vac~265Vac universal input
Non-isolated buck power supply.
The BP8519C integrates a 700V power MOSFET.
With the proprietary loop control technique, it
doesn’t need external compensation cap, and can get
excellent CV regulation. The chip integrates smart
high voltage startup and power supply circuit, so
auxiliary winding could be eliminated. Thus, the
system cost and size are minimized.
The BP8519C utilizes multiple mode control of
PWM & PFM, which contribute to very low standby
power, high efficiency, excellent dynamic response
and minimized audible noise.
The BP8519C is available in SOT23-5 package.
