Calex Surface Mount DC-DC Converters


CALEX announces the SMT Series 1 and 3 watt single and dual output DC-DC Converter families. The 1 watt single output SMT Series offers 5VDC and 12VDC nominal inputs with 5, 9, 12 and 15VDC outputs. The 1 watt dual output SMT Series offers 5VDC and 12VDC nominal inputs with +/-5, +/-9, +/-12 and +/-15VDC outputs. The input range for both the SMT 1 watt singles and duals is +/-10%.

The 1 watt SMT single and dual output converters are all isolated input to output. The isolation voltage is 1000VDC. Efficiencies run as high as 82% for the singles and 80% for the duals. The switching frequency is typically 100kHz. Line regulation is typically +/-1.2% and output noise is typically 60mV peak to peak. Load regulation varies by model but is as low as 5% max for the 15VDC single and dual output models. The operating temperature range is +/-25 degC - +85 deg C ambient. The package size for the 1 watt singles and duals is 0.31" x 0.6" x 0.27"H.

The 3 watt single and dual output SMT models are housed in a 0.58" x 1.27" x 0.4"H package. The 3 watt SMT Series offers nominal inputs of 12, 24 and 48VDC. The input range is 9 - 18, 18 - 36 and 36 - 75 respectively. Single output options include 3.3, 5, 12 and 15VDC. Dual output options are +/-5, +/-12 and +/-15VDC. Isolation voltage for the 3 watt SMT singles and duals is 1500VDC. Efficiencies run as high as 83% for the single output models and 82% for the dual output models.
