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)
