AP64352 - 3.5A LOW IQ SYNCHRONOUS BUCK

General Description

The AP64352 is a 3.5A, synchronous buck converter with a wide input voltage range of 3.8V to 40V.

The device fully integrates a 75mΩ highside power MOSFET and a 45mΩ low-side 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. The device is available in an SO-8EP package. Features.
  • VIN 3.8V to 40V.
  • 3.5A Continuous Output Current.
  • 0.8V ± 1% Reference Voltage.
  • 22µA Low Quiescent Current (Pulse Frequency Modulation).
  • Programmable Switching Frequency: 100kHz to 2.2MHz.
  • External Clock Synchronization: 100kHz to.

AP64352 3.8V TO 40V INPUT, 3.5A LOW IQ SYNCHRONOUS BUCK WITH INTERNAL COMPENSATION Description Pin Assignments The AP64352 is a 3.5A, synchronous buck converter with a wide input voltage range of 3.8V to 40V. The device fully integrates a 75mΩ highside power MOSFET and a 45mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP64352 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 AP64352 design is optimized for Electromagnetic Interference (EMI) reduction.
