Notes:
1. A reversed power source could damage the unit.
4. The VADJ input should be left open if not used. Grounding VADJ will shut the unit
down. Connecting VADJ to VIN may damage the unit.
2. No connection should be made between input ground and the output.
3. These are step-down devices, the maximum output open voltage is
equal to the input voltage.
5. Exceeding the specified maximum output power could cause damage to the unit.
Typical Connection: AC/DC Input
Connection Notes:
To comply with EN61000-4-5, a TVS should be installed before the input filter components. A 3.0SMCJ15A or SMCJ16A is recommended. The TVS max clamping voltage (@max peak pulse
current VC) must be
20V. This will prevent any surge from exceeding the maximum input of the driver (20 VDC). Exceeding the maximum input rating could damage the driver.
The filter shown (C1, C2, C3 and L1) will help to meet conducted emission requirements. With the addition of the filter, the unit should meet the levels of EN 55015.
Connection Notes:
This is a distributed (or two-stage) AC connection. In this configuration, the AC line in (85 to 264 VAC) is connected to the MPM-20S-15EPB, a compact 20W AC/DC
power supply. The MPM-20S-15EPB provides a tightly regulated 15 VDC output at 1,330 mA. The 15 VDC output powers the LED driver.
The two stage approach can simplify the safety approval process (most AC/DC power supplies on the market are approved to EN 60950) and may increase design flex-
ibility. Besides the output voltage/current ratings, other specifications to consider when selecting the input AC/DC supply might include input range, case size, efficiency,
EMI ratings and operating temperature range.
Note: The output current adjustment circuit shown in both connection diagrams is discussed on page 4.
