FAIRCHILD  ML4800CP ML4800  Power Factor Correction and PWM Controller Combo 16-Pin PDIP

Descrption:

The ML4800CP 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 IEC1000-3-2 specification. Intended as a BiCMOS version of the industry-standard ML4824, the ML4800 includes circuits for the implementation of leading edge, average current, "boost" type power factor correction and a trailing edge, pulse width modulator (PWM). It also includes a TriFault Detect function to help ensure that no unsafe conditions will result from single component failure in the PFC. Gate-drivers with 1A capabilities minimize the need for external driver circuits. Low power requirements improve efficiency and reduce component costs.

Features:

• Internally synchronized leading-edge PFC and trailingedge PWM in one IC
• TriFault Detect for UL1950 compliance and enhanced safety
• Slew rate enhanced transconductance error amplifier for ultra-fast PFC response
• Low power: 200μA startup current, 5.5mA operating current
• Low total harmonic distortion, high PF
• Reduced ripple current in storage capacitor between PFC and PWM sections
• Average current, continuous boost leading edge PFC
• PWM configurable for current-mode or voltage mode operation
• Current fed gain modulator for improved noise immunity
• Overvoltage and brown-out protection, UVLO, and soft start
