Description

DM0265R is Green Mode Fairchild Power Switch (FPSTM). The FSDx0265RN(x stands for M, H) are integrated Pulse Width Modulators (PWM) and Sense FETs specifically designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external components. Both devices are integrated high voltage power switching regulators which combine an avalanche rugged Sense FET with a current mode PWM control block. The integrated PWM controller features include: a fixed oscillator with frequency modulation for reduced EMI, Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB), optimized gate turn-on/turn-off driver, Thermal Shut Down (TSD) protection, Abnormal Over Current Protection (AOCP) and temperature compensated precision current sources for loop compensation and fault protection circuitry.

Features

• Internal Avalanche Rugged Sense FET

• Consumes only 0.65W at 240VAC & 0.3W load with Advanced Burst-Mode Operation

CM6800T datasheet pdf

Description

The CM6800T is a turbo-speed PFC and a Green PWM controller. It is designed to further increase power supply efficiency while using the relatively lower 380V Bulk Capacitor value.

“PFC” stands for Power Factor Correction, and a “Green PWM controller” typically refers to a Pulse Width Modulation (PWM) controller designed for energy-efficient or “green” power management. These are two separate components or technologies often used together in power electronics to improve the efficiency and environmental friendliness of electrical systems.

Advanced performances :

1. Hold Up time can be increased ~ 30% from the existing 6800 power supply

2. Turbo Speed PFC may reduce 420 Bulk Capacitor size

3. 420V bulk capacitor value may be reduced and PFC Boost Capacitor ripple current can be reduced

4. No Load Consumption can be reduced 290mW at 270VAC

5. Better Power Factor and Better THD

6. Clean Digital PFC Brown Out

7. PWM transformer size can be smaller

Features

1. Patents Pending

2. Pin to pin compatible with CM6802 family, CM6800 family, and ML4800 family

3. 23V Bi-CMOS process

4. Designed for EPA/85+ efficiency

5. Digitized Exactly 50% Maximum PWM Duty Cycle
