Description
The ML4819CP is a complete boost mode power factor controller (PFC) with a PWM controller. It is designed to provide high current and high slew rate for quick charging and discharging of MOSFET gates. The ML4819CP features a precision buffered 5V reference, large oscillator amplitude for improved noise immunity, and a programmable ramp compensation circuit. It also incorporates an over-voltage comparator to prevent output "runaway" and an under-voltage lockout circuit with 6V hysteresis.
Specifications and features
- Two 1A peak current totem-pole output drivers
- Precision buffered 5V reference (±1%)
- Large oscillator amplitude for better noise immunity
- Precision duty cycle limit for PWM section
- Current input gain modulator improves noise immunity
- Programmable Ramp Compensation circuit
- Over-Voltage comparator helps prevent output "runaway"
- Wide common mode range in current sense compensators for better noise immunity
- Under-Voltage Lockout circuit with 6V hysteresis
Application Scenarios
The ML4819CP is suitable for applications that require boost mode power factor control and PWM control for a second stage converter. It is commonly used in electronic devices that need high current and high slew rate for efficient charging and discharging of MOSFET gates. The ML4819CP is also designed with noise immunity in mind, making it a reliable option for systems that are sensitive to noise interference.
