40V, 2.2MHz Synchronous Buck Converters From Diodes Incorporated Deliver High Efficiency Across All Loads

PLANO, Texas--()--Diodes Incorporated (Nasdaq: DIOD) today announced the introduction of five synchronous buck converters with integrated high- and low-side MOSFETs, providing point-of-load (PoL) solutions with a continuous output current of either 3.5A or 5A. The devices feature proprietary gate driver technology, delivering superior EMI performance in step-down DC-DC conversion for consumer, industrial, networking, and automotive applications.

The AP64350, AP64351, and AP64352 operate with a quiescent current (Iq) of 22μA, while the Iq of the AP64500 and AP64501 is just 25μA. All devices feature low RDS(ON) and operate from a supply voltage of between 3.8V and 40V and provide a low dropout (LDO) mode. As well as the optimized gate driver design, the parts also employ a frequency spread spectrum topology to further reduce EMI.

In addition, the AP64351 and AP64501 implement programmable soft-start, which can mitigate the effects of inrush currents as well as tracking, allowing power sequencing to be implemented more efficiently.

Switching frequencies are adjustable between 100kHz and 2.2MHz. This adjustable frequency allows engineers to select the most appropriate configuration for their application, based on efficiency, size of external components, or RF compatibility with other system-level functions.

The AP64350, AP64351, AP64352, AP64500, and AP64501 are available in the SO-8EP package.
