Datasheet

AP3429AKTTR-G1 – Buck Switching Regulator IC 2A SOT-23-5

The AP3429AKTTR-G1 from Diodes Incorporated is a high-efficiency 2A synchronous step-down (buck) DC-DC converter designed for compact, low-power, and battery-operated systems. Operating over a wide input voltage range of 2.7V to 5.5V, it efficiently converts single-cell Li-Ion/Li-Polymer or multiple alkaline/NiMH cell power sources into regulated outputs ranging from 0.6V up to VIN. This device integrates both the power switch and synchronous rectifier, reducing external component count and achieving excellent efficiency and thermal performance. It uses constant-frequency PWM control at heavy loads, ensuring fast transient response and stable operation without the need for external compensation components. At lighter loads, the AP3429A maintains high efficiency with a typical quiescent current of just 90uA, while in shutdown mode, the current drops below 1uA to conserve battery life.

The AP3429AKTTR-G1 also includes comprehensive protection features such as over-temperature protection (OTP), short-circuit protection (SCP), and under-voltage lockout (UVLO) to prevent deep battery discharge and enhance overall system reliability. Its 100% duty cycle operation ensures low dropout performance, making it ideal for high-current, low-voltage power rails in portable devices and embedded applications.

Key Features:

  • Wide Input Voltage Range: 2.7V to 5.5V, ideal for single-cell Li-Ion or multi-cell battery systems.
  • High Output Current: Supports up to 2A continuous output.
  • Adjustable Output Voltage: From 0.6V to VIN for versatile system requirements.
  • High Efficiency: Synchronous rectification with ultra-low RDS(ON) MOSFETs for minimal power loss.
  • Low Quiescent Current: 90µA typical at no load for extended battery life.
  • Low Shutdown Current: Less than 1µA when disabled for minimal standby power.
  • Constant Frequency PWM: Provides excellent stability and transient response.
  • 100% Duty Cycle Operation: Ensures low dropout performance under full load.
  • Integrated Protection: Includes OTP, SCP, and UVLO for safe operation.
  • Compact SOT-23-5 Package: Saves board space and simplifies PCB layout.
  • Applications: Ideal for portable electronics, communication devices, battery-powered systems, and embedded controllers.
