Description
The Bel SRDC-16D120 module is one in a series of non-isolated, DC/DC power converters that operate from a wide input range of 3V minimum to 15V maximum. This converter is available with 1.2V output. It uses a low profile, surface mount DIP package for ease of layout and space savings. 16A maximum output is also provided. Standard features include remote on/off, over current and short circuit protection, programmable UVLO and output voltage adjust. Optional features include two-wire remote sense or single-ended remote sense with a good power signal. This module also makes use of adaptive positioning to improve transient response performance. It may be used almost anywhere low voltage silicon is employed and a 3 to 15V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.

The enable pin performs two functions, remote on/off and programmable under voltage lockout. The factory set UVLO point is 3.0V typical, but can be adjusted upward with the addition of a single external resistor located from the enable pin to ground. Turning the converter on and off is accomplished using an open collector/drain device as a switch. The enable pin is internally pulled up to Vin through a 12.1K resistor and the pin’s logic is active high. Note: Input capacitance 100µF/16V, ESR = 0.03 Ω max at 100kHz @ 25° C. 1. With simulated source impedance of 500nH, 5Hz to 20MHz. 2. UVLO is adjustable by terminating on/off pin to ground per the termination resistance table on page 7. retemaraP lobmyS niM lacipyT xaM tinU egatloVtupnIsuounitnoCn iV3 .0- 51V egatloVlanimreTelbanEtuptuO 1 netuoV3 .0- 6V erutarepmeTtneibmAb maT0 07C ° erutarepmeTegarotSr otsT0 4- 501C ° retemaraP lobmyS niM lacipyT xaM stinU egatloVtupnIgnitarepOn iV1 .3 51V (tnerruCtupnI) V3.3=niVn iI 2.7A (tnerruCtupnI) V0.5=niVn iI 5A (tnerruCtupnI) V0.21=niVn iI 1.2A (tnerruCtupnIdaoLoN) V3.3=niVn iI 002A m (tnerruCtupnIdaoLoN) V0.5=niVn iI 051A m (tnerruCtupnIdaoLoN) V0.21=niVn iI 001A m tnerruCelppiRdetcelfeRtupnI 1 05A m smr )P-P(tnerruCelppiRdetcelfeRtupnI 1 001k pAm I2 tneisnarTtnerruChsurnIt 1.0A 2s dlohserhTegatloVnOnruT 2 29.2 V dlohserhTegatloVffOnruT8 .25 8.20 9.2V
