Fairchild Intros FAN2011/FAN2012 DC-DC Buck Regulators
Fairchild Semiconductor International Inc. (South Portland, ME) introduced two new high-efficiency, 1.5 A, synchronous dc-dc buck regulators, the FAN2011 and FAN2012, which improve power densities and minimize board space in systems such as set-top boxes, hard disk drives, point-of-load (POL) power and communications equipment.
Suitable for low-power applications, the FAN2011 is always "on," while the FAN2012 has an enable pin that offers the ability to implement power management schemes for power conservation. The new synchronous PWM, current-mode dc-dc converters offer a high efficiency of 95%, continuous load current of 1.5 A, a high operating frequency of 1.3 MHz, on-chip MOSFETs, and an adjustable output voltage from 0.8 V to VIN.
The devices are offered tiny, six-terminal, 3 mm x 3 mm, lead-free, molded leadless packages (MLP) that meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B, and that are compliant with European Union requirements. Available now, the FAN2011 is priced at $0.74 and the FAN2012 is priced at $0.79 for 1,000-piece quantities. Delivery is eight weeks ARO.
