Datasheet

PAM2305AABADJ – Buck Switching Regulator IC 1A SOT-23-5

The PAM2305AABADJ from Diodes Incorporated is a highly efficient 1A synchronous step-down (buck) DC-DC converter designed for compact, battery-powered, and portable systems. Operating across an input voltage range of 2.5V to 5.5V, it efficiently converts single-cell Li-Ion/Li-Polymer or multi-cell battery sources into regulated low-voltage outputs ranging from 0.6V up to VIN. Using a current-mode control architecture, the PAM2305 ensures fast transient response and excellent load regulation. At heavy loads, it operates in PWM mode for high stability, while at light loads, it automatically enters Pulse-Skipping Modulation (PSM) mode to reduce quiescent current and extend battery life. The converter integrates both the high-side power switch and synchronous rectifier, minimizing external components and achieving efficiencies up to 96%. The 1.5MHz fixed switching frequency enables the use of small inductors and capacitors for a compact PCB layout. The device also features soft-start, short-circuit protection, thermal shutdown, and undervoltage lockout (UVLO) for robust operation and design safety. Packaged in a tiny SOT-23-5 (TSOT25), the PAM2305AABADJ is ideal for space-limited applications requiring high performance and reliability.

Key Features:

  • Wide Input Range: 2.5V to 5.5V, compatible with Li-Ion, NiMH, and USB power sources.
  • High Efficiency: Up to 96% with internal synchronous rectifier.
  • Output Current: Supports up to 1A continuous load.
  • Adjustable Output Voltage: 0.6V to VIN for versatile system designs.
  • Low Quiescent Current: Only 40uA typical, ensuring long battery life.
  • 1.5MHz Fixed Frequency: Enables use of small external components.
  • Soft-Start: Limits inrush current during power-up.
  • PSM Mode: Reduces power loss at light loads.
  • Comprehensive Protection: Includes UVLO, short-circuit protection, and thermal shutdown.
  • Compact Package: 5-pin SOT-23 (TSOT25) for space-constrained applications.
  • Applications: Ideal for portable electronics, handheld instruments, USB-powered devices, and battery-based systems.
