The reduction in size of the inductor and other standard external components resulting from the higher operating frequency, combined with the converter's compact SO-8 packaging and integrated low RDSON power MOSFET switch means significant board space savings can be achieved.  A minimized external component count also provides increased flexibility in circuit design.

Characterized by its low series resistance, the AP5101 delivers a constant output current up to a peak of 1.5 A for an efficiency as high as 92 percent, over a wide input supply range of 4.75 V to 22 V.  A fast transient response eases loop stabilisation requirements and the output is adjustable from 0.81V to 15V.

The AP5101 is self-protected through cycle-by-cycle current limiting and thermal shut down protection, ensuring long term product reliability.  The converter has an enable pin allowing it to be switched off into a standby mode, consuming just 0.1 µA.

Pricing

The AP5101 buck converter from Diodes Incorporated is priced at 0.19 US Dollars each in 10,000 piece quantities.
