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 power-switching regulator that combines an avalanche rugged
SenseFET with a current mode PWM control block.
1. Internal Avalanche Rugged SenseFET
2. Low Start-up Current (max. 40µA)
3. Low Power Consumption; under 1W at 240VAC and 0.4W Load
4. Precise Fixed Operating Frequency (66kHz)
5. Frequency Modulation for Low EMI
6. Pulse-by-Pulse Current Limiting (Adjustable)
7. Over-Voltage Protection (OVP)
8. Overload Protection (OLP)
1. SMPS for VCR, SVR, STB, DVD, and DVCD
3. SMPS for LCD Monitor
