Description
The ML4812IP is an IC chip designed to facilitate a peak current control boost power factor correction system. The circuit comprises a precision reference, gain modulator, error amplifier, overvoltage protection, ramp compensation as well as a high current output. The chip has programmable ramp compensation circuit and a 1A peak current totem-pole output drive. The device has a wide common mode range in current sense comparators for improved noise immunity.
Specifications and features
- Product Category: IC Chips
- Precision buffered 5V reference (±0.5%)
- Current-input gain modulator reduces external components and improves noise immunity
- Programmable ramp compensation circuit
- 1A peak current totem-pole output drive
- Overvoltage comparator helps prevent output "runaway"
- Large oscillator amplitude for better noise immunity.
Application Scenarios
The IC chip ML4812IP is generally used in the peak current control boost power factor correction system. It is particularly useful in applications with sinusoidal line voltage times the output of the error amplifier which regulates the output DC voltage.
Comparison
Advantages- Improves noise immunity with current-input gain modulator and wide common mode range in current sense comparators.
- Has a programmable ramp compensation circuit, enabling stable operation when the duty cycle exceeds 50%.
- Includes overvoltage comparator to prevent output voltage "runaway."
DisadvantagesNo known disadvantages at the moment.
