POWER FACTOR CORRECTION CONTROLLER
POWER
M8128A
GENERAL DESCRIPTION
The M8128A provides simple and high performance active power factor correction. The M8128A provides a controlled on-time
to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is
programmable to ensure safe operation during AC brownouts. An innovative multi-vector error amplifier is built in to provide
rapid transient response and precise output voltage clamping. A built in circuit will disable the controller if the output feedback
loop is opened.
FEATURES
‧ Low Input Current THD
‧ Controlled On-Time PWM
‧ Zero-Current Detection
‧ Leading-Edge Blanking instead of RC Filtering
‧ Low Start-up Current
‧ Low Operating Current
‧ Transition mode operation
‧ Under Voltage Lockout with Hystersis
‧ Feedback Open Loop Protection
‧ Programmable Maximum On-Time
‧ 8-pin DIP or 8-pin SOP
APPLICATIONS
‧ Electronic Lamp Ballasts
‧ AC-DC Switching Mode Power Converters
‧ Open Frame Power Supplies and Power Adapters
‧ Flyback Power Converters with ZCS/ZVS
