Features Low cost 10 amp output current 94 % efficiency Industry-standard pin-out Low 0.6 profile Remote sense Trim function Short-circuit protection with auto-restart Fast transient response High-temperature operation 75 W/in3 power density Remote enable Output precharge capability Patents 5,770,940; 5,978,195; 6,127,814 SC10A DAC Series - Power Module General Information The SC10A DAC is a low-cost, 10 amp, non-isolated DC-DC converter with an amazingly small footprint. Designed for today's high power microprocessors, the SC15A accepts a 5 V input and a DAC controlled output from 1.25 V to 3.5 V. Using Bourns proprietary V2TM architecture, the SC10A DAC provides ultrafast transient response, improved line and load regulation, and very high efficiency. It also incorporates short-circuit protection, Enable / Disable control, output voltage trim, and remote sense.
