| Product Data Sheet 5 VDC INPUT, 3.3 VDC OUTPUT DC/DC CONVERTER SS26 (SuperSIPTM) Description The SS26 (SuperSIPTM) DC/DC converter accepts a regulated 5V input (10%) and provides 1.8Vdc to 3.6Vdc at 6A. The circuit is optimized for high efficiency and fast load transient response needed by telecom, DSP and , microprocessor applications. Advanced thermal design, monolithic power circuitry, planar magnetics, and synchronous rectification result in outstanding performance and value. Pins are staked for wave solderability. Multiple programming, power good and on/ off options allow superior flexibility and drop in compatibility for most existing designs. Features q Non isolated DC/DC Converter designed to operate from a regulated 5V bus q Output voltage Range: 1.8V - 3.6V q Easy resistive programming for desired output q No resistive programming gives 3.3 Vdc output q Wave solderable More product information and application notes are available on our website at www.cdpowerelectronics.com Internet: http://www.cdpowerelectronics.com Power Electronics Division, United States 3400 E Britannia Drive, Tucson, Arizona 85706 Phone: 520.295.4100 Fax: 520.770.9369 SUPERSIP26 11/99 REV C Power Electronics Division, Europe C&D Technologies (Power Electronics) Ltd. 132 Shannon Industrial Estate, Shannon, Co.

Page 2 SUPERSIP26 11/99 REV C Programming To program the SS26 SuperSIPTM for Vout<3.3, connect resistor across pins 8 (TRIM) and 1(Vo). For Vout>3.3, resistor is connected across pins 8 and 4 (Gnd). Thermal Design Guide Locate your operating current, read the junction temp rise from the graph and add to your maximum ambient. 135C is the maximum allowable operating junction temperature. Test conditions: Device soldered into 4" x 4" PCB, 2 sided with power and ground planes for heat conduction. Due to the difficulty in predicting the thermal effects of airflow velocity and direction, and thermal conduction through ground planes it is important that the SS26 SuperSIPTM be evaluated thermally in each application. For high ambient temperature/high current application please request our Application Note 35-118-01, "Accurate Measurements of SS26 SuperSIPTM Junction Temperature", for further assistance.
