Notes:
1. A reversed power source could 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.
Typical Connection: DC/DC Input
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.
5. Exceeding the specified maximum output power could cause damage to the unit.
www.DataSheet.net/
Connection Notes:
To comply with EN61000-4-5, a TVS should be installed before the input filter components. A 3.0SMCJ48A or SMCJ48A is recommended. The TVS max clamping voltage (@max peak pulse
current VC) must be ϹϮ60V. This will prevent any surge from exceeding the maximum input of the driver (65 VDC). Exceeding the maximum input rating could damage the driver.
The filter shown (C1, C2 and L1) will help to meet conducted emission requirements. With the addition of the filter, the unit should meet the levels of EN 55015.
Typical Connection: AC/DC Input
Connection Notes:
This is a distributed (or two-stage) AC connection. In this configuration, the AC line in (90 to 264 VAC) is connected to the MPM-04S-12, a miniature 4W AC/DC power
supply. The MPM-04S-12 provides a tightly regulated 12 VDC output at 333 mA. The 12 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 power, other specifications to consider when selecting the input AC/DC supply would include input range, safety approvals, PFC rating (which
may be needed for various system energy ratings) and operating temperature range.
Note: The output current adjustment circuit shown in both connection diagrams is discussed on page 4.
