The key feature of the Green Mode Fairchild Power Switch ICs is their energy-saving capability, which helps improve overall power efficiency and reduce standby power consumption. They are designed to enter a low-power mode when the load is light or inactive, hence the “Green Mode” designation. This feature can lead to power savings and help meet energy efficiency regulations.
These power switch ICs typically integrate a power MOSFET, a PWM controller, protection features, and other circuitry into a single chip. They offer benefits such as built-in overcurrent protection, overvoltage protection, and thermal shutdown, ensuring safe and reliable operation.
Part Number: DM0465R, FSDM0465R, DMO465R
Function: Green Mode Fairchild Power Switch
Package: D2-PAK-6L, I2-PAK-6L, TO-220-6L Type
Manufacturer: Fairchild Semiconductor
The DM0465R is an integrated Pulse-Width Modulator (PWM) and SenseFET specifically designed for high-performance offline Switch Mode Power Supplies (SMPS) with minimal external components. This device is an integrated high-voltage powerswitching regulator that combines an avalanche rugged SenseFET with a current mode PWM control block. The PWM controller includes an integrated fixed-frequency oscillator, under-voltage lockout, leading edge blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current sources for a
loop compensation, and self-protection circuitry.
Compared with a discrete MOSFET and PWM controller solution, it can reduce total cost, component count, size, and weight while simultaneously increasing efficiency,
productivity, and system reliability. This device is a basic platform well suited for cost-effective designs of flyback converters.
