20 Watt, SLV20 DC-DC Single Output Series

1.00"x 2.0"x .400" OPEN FRAME CONSTRUCTION
20W MAC20 DC-DC
FEATURES

The SLV20 series of DC-DC converters have been designed as a surface-mount and thru-hole solution for a wide range of applications where low voltage, high efficiency and ease of assembly are needed. The SLV20 series packs up to 20 watts of power in 1.00" x 2.0" x .400" open frame construction and operating temperatures of -40C to +105C. All models are designed to meet UL1950, CSA950 and EN 60950.

NOTES:
  1. Output Power is up to 20W, see Io rating on "Model Selection Guide".
  2. Model numbers are SMD type pin configuration, replace suffix SM with TH for Thru-hle type.
  3. Typical start-up for 12Vin models is 9V. Maximum startup is 9.5V.
  4. Operation is allowed to No-Load however operation below 10% load may cause ripple and noise to exceed spec.
