Specifications of LM3404MREVAL

• Current - Output / Channel: 1A
• Outputs And Type: 1, Non-Isolated
• Voltage - Output: 37V
• Features: Dimmable
• Voltage - Input: 6 ~ 42 V
• Utilized Ic / Part: LM3404
• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

The logic of DIM is direct, hence the LM3404HV will deliver
regulated output current when the voltage at DIM is high, and
the current output is disabled when the voltage at DIM is low.
Connecting a constant logic low will disable the output, and
the LM3404/04HV is enabled if the DIM pin is open-circuited.
The DIM function disables only the power MOSFET, leaving
all other circuit blocks functioning to minimize the converter
response time.
