AP64351Q
AUTOMOTIVE-COMPLIANT, 40V, 3.5A SYNCHRONOUS BUCK WITH PROGRAMMABLE SOFT-START TIME Description Pin Assignments The AP64351Q is an automotive-compliant, 3.5A, synchronous buck
converter with a wide input voltage range of 3.8V to 40V. The device
fully integrates a 75mΩ high-side power MOSFET and a 45mΩ lowside power MOSFET to provide high-efficiency step-down DC-DC
conversion. (Top View)
(Top
View) The AP64351Q device is easily used by minimizing the external
component count due to its adoption of peak current mode control. BST 1 VIN 2 8 SW 7 GND EXPOSED PAD
9 The AP64351Q design is optimized for Electromagnetic Interference
(EMI) reduction. The device has a proprietary gate driver scheme to
resist switching node ringing without sacrificing MOSFET turn-on and
turn-off times, which reduces high-frequency radiated EMI noise
caused by MOSFET switching. AP64351Q also features Frequency
Spread Spectrum (FSS) with a switching frequency jitter of ±6%,
which reduces EMI by not allowing emitted energy to stay in any one
frequency for a significant period of time. EN 3 6 COMP SS 4 5 FB SO-8EP
