The Diodes Advantage

The AP6320xQ/AP6330xQ provide high-efficiency

DC-DC conversion for automotive POL applications.

The automotive-compliant* AP6320xQ

and AP6330xQ are 2A and 3A

respectively, synchronous buck

converters with a wide input voltage

range of 3.8V to 32V, and are AEC-

Q100 Grade 1 qualified.

The AP6320xQ and AP6330xQ

integrate low resistance high- and low-

side power MOSFETs to provide high-

efficiency step-down DC-DC

conversion.

The devices minimize external

component count due to their adoption

of peak current mode control and an

integrated loop compensation network.

This low component count provides

ease of design.

They have been optimized for

electromagnetic interference (EMI)

reduction, which includes a proprietary

gate driver scheme that resists

switching node ringing without

sacrificing MOSFET turn-on and turn-

off times.

The AP63200Q, AP63203Q,

AP63205Q, and AP63300Q also

feature frequency spread spectrum

(FSS) which further reduces EMI by

preventing emitted energy from staying

in any one frequency for a significant

period of time.

The devices are available in a low-

profile TSOT26 package.
