Description
The CM6800X is an integrated circuit (IC) controller for Switched Mode Power Supplies (SMPS), belonging to the category of IC Chips. It is designed to perform Power Factor Correction (PFC) for SMPS, which helps to use smaller and cost-effective bulk capacitors, reduce power line loading and stress on the switching FETs, and generate a power supply that fully complies with the IEC-1000-3-2 specifications.
Specifications and features
- Pin to pin compatible with ML4800 and FAN4800
- Includes circuits for the implementation of leading edge, average current, "boost" type power factor correction and a trailing edge, pulse width modulator (PWM).
- Gate-driver with 1A capabilities minimizes the need for external driver circuits.
- Low power requirements improve efficiency and reduce component costs.
- The IC is designed using a 23V Bi-CMOS process and internally synchronized leading edge PFC and trailing edge PWM in one IC.
- The IC operates with low start-up current (100μA typ.) and low operating current (3.0mA type.).
- The IC has low total harmonic distortion, high power factor, and reduces ripple current in the storage capacitor between the PFC and PWM sections.
- The IC has an average current, continuous, or discontinuous boost leading edge PFC and PWM configurable for current mode or voltage mode operation.
- The IC provides features like VCC OVP Comparator, Low Power Detect Comparator, Current fed gain modulator for improved noise immunity, Brown-out control, over-voltage protection, UVLO, and soft start, and Reference OK.
Application Scenarios
The CM6800X is widely used in switched-mode power supplies used in various electronic devices like computers, televisions, and communication devices. It is a crucial component in the power supply unit that converts AC voltage to DC voltage. CM6800X makes the SMPS energy-efficient, leading to a smaller carbon footprint and reduced energy costs.
Comparison
Advantages- CM6800X has a high power factor correction (PFC) and low Total Harmonic Distortion (THD), making it more energy-efficient.
- It is cost-effective as it reduces component cost and uses smaller bulk capacitors, which further reduces the product's overall cost.
- The IC has built-in protection features like over-voltage protection, UVLO, and soft start, leading to better longevity and reliability of the product.
- It has multiple modes of operations and is designed to work under low power requirements, making it an ideal power control system for various electronic devices.
Disadvantages- CM6800X has a low operating frequency range and has limitations in high power applications.
- The IC might have compatibility issues with some older models of SMPS.
