OBSOLETE PRODUCT Contact factory for replacement model 5 Vdc Input, 3.3 Vdc Output DC/DC Converter SuperSIP™ Description Features ● Non isolated DC/DC Converter designed to operate from a regulated 5V bus The 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. ● Output voltage Range: 1.8V - 3.6V ● Easy resistive programming for desired output ● No resistive programming gives 3.3 Vdc output ● Wave solderable Page 1 SUPERSIP 8/98 REV C Electrical Specifications Unless otherwise specified, operating conditions are as follows: Vin=5V, Vo=3.3V, Io=6A, TA=25°C, Cin=100µF, Co=0F.

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 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 SuperSIPTM Junction Temperature”, for further assistance.
