SC451: PowerStep IV® Portable IMVP-IV® And IMVP-IV+® Single-Phase Power-Supply Controller | Semtech

The SC451 PowerStep IV, IC is a single chip high-perfor- mance Hysteretic PWM Controller With its integrated SmartDriver,, it powers advanced IMVP-IV, and IMVP4+, processors. The SC451 features extended Intel Mobile Volt- age Positioning (IMVP,) to increase battery life by reduc- ing the voltage at the processor when it is heavily loaded. It directly supports Intels SpeedStep, processors for eve longer battery life. The SC451 fully supports the Intel, Geyserville-III core voltage specification. It provides direct deeper sleep mode and boot voltage support. Automat power-save is present to prevent negative current flow the low-side FET during light loading conditions, saving even more power. The high side driver initially turns on with a weak drive to reduce ringing, EMI and capacitive turn-on of the low side. The complete datasheet for this product is restricted to IMVP licensees only.
