Datasheet

AP64350QSP-13 – 3.5A Automotive-Grade Synchronous Buck Switching Regulator IC

The AP64350QSP-13 is a high-efficiency 3.5A synchronous step-down (buck) DC-DC converter designed for automotive and industrial applications requiring reliable and low-noise power delivery. With a wide input voltage range from 3.8V to 40V, the device supports a broad array of power sources, including automotive battery systems and unregulated DC rails. It integrates both high-side (75mohm) and low-side (45mohm) power MOSFETs, providing efficient conversion while minimizing component count and heat generation.

Using a peak current mode control architecture, the AP64350Q simplifies design and ensures fast transient response with minimal external components. Its proprietary gate driver scheme effectively suppresses switching node ringing, reducing high-frequency radiated EMI noise without compromising switching performance. Additionally, the inclusion of Frequency Spread Spectrum (FSS) with +-6% frequency jitter further minimizes EMI by distributing energy across a wider frequency range. Built to meet automotive-grade standards, the AP64350QSP-13 ensures reliable performance in harsh environments, offering superior efficiency, reduced EMI emissions, and robust operation in a compact SOIC-8 package.

Key Features

  • Wide Input Voltage Range: Operates from 3.8V to 40V for flexible system compatibility.
  • High Output Current Capability: Delivers up to 3.5A continuous load current with excellent efficiency.
  • Integrated MOSFETs: 75mΩ high-side and 45mΩ low-side transistors reduce conduction losses and component count.
  • Peak Current Mode Control: Simplifies compensation design while maintaining fast transient response.
  • Optimized for EMI Reduction: Proprietary gate driver scheme minimizes switching noise and ringing.
  • Frequency Spread Spectrum (FSS): +-6% frequency jitter spreads switching energy to reduce EMI emissions.
