Datasheet

AP64500SP-13 – Buck Switching Regulator IC 5A SOIC-8

The AP64500SP-13 from Diodes Incorporated is a high-efficiency, wide-input 5A synchronous step-down (buck) converter designed for robust performance, compact design, and exceptional EMI suppression. With an input voltage range of 3.8V to 40V, it is ideal for a wide range of industrial, automotive, and communication power supply applications. The device integrates a 45mΩ high-side and 20mΩ low-side MOSFET, delivering high conversion efficiency and low thermal losses while minimizing external component count. The AP64500 employs peak current mode control for fast transient response and ease of use. It is optimized for EMI reduction through a proprietary gate driver design that suppresses switching node ringing and minimizes high-frequency radiated noise. Additionally, frequency spread spectrum (FSS) technology introduces a +-6% jitter in the switching frequency (programmable from 100 kHz to 2.2 MHz) to further reduce EMI emissions.

This device maintains up to 85% efficiency at a light load of 5mA thanks to its low quiescent current of just 25µA in Pulse Frequency Modulation (PFM) mode, extending battery life and improving power efficiency in low-load conditions. Advanced protection features include undervoltage lockout (UVLO), output overvoltage protection (OVP), cycle-by-cycle peak current limiting, and thermal shutdown. Packaged in a thermally enhanced SOIC-8EP, the AP64500SP-13 offers excellent heat dissipation and reliability for high-performance power systems.

Key Features:

  • Wide Input Range: Operates from 3.8V to 40V for flexible power rail applications.
  • High Output Capability: Delivers up to 5A continuous load current.
  • Integrated MOSFETs: 45mΩ (high-side) and 20mΩ (low-side) for superior efficiency and reduced losses.
  • High Efficiency: Up to 85% efficiency at 5mA light load for power-sensitive systems.
  • Low Quiescent Current: 25µA in PFM mode for extended battery operation.
  • Programmable Frequency: Adjustable from 100kHz to 2.2MHz, supports external synchronization.
  • Advanced EMI Reduction: Proprietary gate driver and Frequency Spread Spectrum (+-6%) minimize radiated noise.
  • Low-Dropout Mode (LDO): Maintains output regulation during light loads or near-dropout conditions.
  • Comprehensive Protection: Includes UVLO, OVP, cycle-by-cycle current limit, and thermal shutdown.
  • Precision Enable Control: Adjustable UVLO threshold for system-level flexibility.
  • Compact & Thermally Efficient: SOIC-8EP package ensures excellent thermal performance.
