PENTIUM™ AND POWER PC™ SUPPLIES LOW COST SOLUTION FOR 3.3V TO 1.5V CONVERSION SUITABLE FOR APPLICATIONS
WITH STAND BY FEATURE DESCRIPTION
TYPICAL APPLICATION MULTIPOWER BCD TECHNOLOGY HEPTAWATT ORDERING NUMBER: L4956 Designed in BCDII technology, it uses a charge pump technique to have a proper internal N-channel gate drive. An RDSON of 150mV gives a voltage drop of 750mV at 5A of load current. Very fast load transients and ±1% of reference voltage precision makes this device suitable for supplying last micrprocessors generation and low voltage logics. The Heptawatt package enriches the device with auxiliary functions like power good and inhibit.
