HDLV SC5A SERIES Family Description The SC5A is a 5-amp, full-featured, non-isolated DC-DC converter. Designed for 12 V distributed power systems, the SC5A comes in a SIP form factor to minimize board space and maximize power density. It combines an industry-standard pin-out with a mounted height of only 0.5 inches. Using Bourns Switch Power's proprietary V2TM architecture with a 12 V input, the SC5A provides ultrafast transient response, improved line and load regulation, and very high efficiency. Common Specifications Features • 5-amp Output Current • 94 % Efficiency • Industry-standard Pin-out • Low 0.5 " Profile • Non-isolated Output • Remote Sense • Remote Enable • Short-Circuit Protection with Auto restart • Trim Function • Fast Transient Response • High-temperature Operation • 60 W/in 3 Power Density Min Input Voltage Current Remote Enable High = Disable Low = Enable Current 9 12 2.4 Output Current 0 Sense Compensation Voltage Setpoint Accuracy Voltage Trim Range -10 Line Regulation Load Regulation Temp Regulation Current Limit 6 Dynamic Response 0 to 100 % load Patents 5,770,940 5,978,195 Nom Max 100 to 0 % load ±1.4 Temperature Regulation General MTBF Operating Temperature Storage Temperature Switching Frequency Vdc A 10-16 V for SC5A-12S5 5.5 0.7 20 Vdc Vdc mA Source 500 µA Open=Enable Disabled 5 50 ±2.3 +10 A mV %Vnom %Vnom %Vnom %Vnom %Vnom/°C A mV µs mV µs ±0.02 %Vout/°C 1,878 -25 -55 85 125 500 Notes 16 3 ±0.2 ±0.1 .005 200 19 200 19 Units k Hrs °C °C kHz ∆i/∆t = 3 A/µs ∆i/∆t = 3 A/µs 25°C, 80 % load, 100 lfm Asia-Pacific: TEL +886- (0)2 25624117 • FAX +886- (0)2 25624116 Europe: TEL +41-41 768 5555 • FAX +41-41 768 5510 The Americas: TEL +1-951 781 5500 • FAX +1-951 781-5700 Reliable Electronic Solutions www.bourns.com Specifications are subject to change without notice.
