AP64352Q - 3.5A SYNCHRONOUS BUCK

General Description

The AP64352Q 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.

Key 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. Pin Assignments BST 1 VIN 2 EN 3 RT/CLK 4 (T(oTopp VVieieww) ).

AP64352Q AUTOMOTIVE-COMPLIANT, 40V, 3.5A SYNCHRONOUS BUCK WITH INTERNAL COMPENSATION Description The AP64352Q 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. The AP64352Q device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated loop compensation network. The AP64352Q design is optimized for Electromagnetic Interference (EMI) reduction.
