ML4841CP
ML4841CP - Brand New onsemi PFC (Power Factor Correction)
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The ML4841 is a controller for power factor corrected, switched mode power
supplies. Power Factor Correction (PFC) allows the use of smaller, lower cost
bulk capacitors, reduces power line loading and stress on the switching FETs,
and results in a power supply that fully complies with IEC1000-2-3
specifications. The ML4841 includes circuits for the implementation of a
leading edge, average current, “boost” type power factor correction, and a
trailing edge, pulse width modulator (PWM).
The PFC frequency of the ML4841 is automatically set at half that of the PWM
frequency generated by the internal oscillator. This technique allows the user
to design with smaller output components while maintaining the optimum
operating frequency for the PFC. An over-voltage comparator shuts down the PFC
section in the event of a sudden decrease in load. The PFC section also
includes peak current limiting and input voltage brown-out protection.
Features
• Internally synchronized PFC and PWM in one IC
• Low total harmonic distortion
• Reduces ripple current in the storage capacitor between
the PFC and PWM sections
• Average current, continuous mode, boost type, leading
edge PFC
• High efficiency trailing edge PWM can be configured for
current mode or voltage mode operation
• Average line voltage compensation with brown-out control
• PFC overvoltage comparator eliminates output
“runaway” due to load removal
• Current fed multiplier for improved noise immunity
• Overvoltage protection, UVLO, and soft start
