DESCRIPTION
The YF/YFW Series of DC/DC converters perform over an ultra-wide input voltage range (2:1 and 4:1),
providing indefinite short circuit and overvoltage protection. Single, dual, and triple outputs are available.
This design technology provides up to 20 watts of output power in a 1.60” x 2.0” x 0.40” case. These current
mode control forward converters are designed for improved transient response and reduced stress on
switching components and do not require external input filtering, making it a preferred source over industry
alternatives.

NOTES
Typical value at nominal input voltage and full load.
Typical value at nominal input voltage and no load.
Maximum value at nominal input and full load.
Test by minimum Vin and constant resistive load.
The output requires a minimum loading on the output to maintain specified regulation. Operation under no-load condition will not damage these
devices, however they may not meet all listed specifications.
(6) Cross Regulation: Dual Output-Asymmetrical load 25% to 100% full load.
Triple output- 3.3V/5V 100% load and one of auxiliary 100% load, other auxiliary load change from 25% to 100% load.
(7) The ON/OFF control pin voltage is referenced to –Vin.
(8) Heatsink is optional (for operating temperature range please see derating curve. Contact factory for details.
(9) The YF/YFW series can meet EN55022 Class A with an external capacitor in parallel with the input pins.
Recommended: 12Vin: 6.8µF/50V 1812 MLCC.
24Vin: N/A
48Vin:2.2µF/100V 1812 MLCC
(10) An external filter capacitor is required if the module has to meet EN61000-4-5.
The filter capacitor Wall Industries suggests is Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ.
(11) The YF Series is a 2:1 wide input range of 18~36VDc and 36~75CSX, the YFW Series is 4:1 ultra wide input range of 9~36VDC and 18~75VDC.
(12) This product is Listed to applicable standards and requirements by UL.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
*Due to advances in technology, specifications subject to change without notice.
