TPS62743YFPR** is a high-efficiency, ultra-low power step-down converter manufactured by **Texas Instruments (TI)**.

The TPS62743YFPR is a high-efficiency, ultra-low power step-down converter manufactured by Texas Instruments (TI).

Key Specifications:

  • Input Voltage Range: 2.2V to 5.5V
  • Output Voltage Range: Adjustable from 1.8V to 3.3V (factory preset options available)
  • Output Current: Up to 300mA
  • Quiescent Current: 350nA (typical)
  • Switching Frequency: 2.25MHz (typical)
  • Efficiency: Up to 95% (depending on load conditions)
  • Operating Temperature Range: -40°C to +85°C
  • Package: DSBGA-12 (1.6mm x 1.6mm)

Descriptions:

The TPS62743YFPR is a synchronous buck converter optimized for ultra-low-power applications, such as battery-powered IoT devices, wearables, and energy harvesting systems. It features Pulse Frequency Modulation (PFM) for high efficiency at light loads and Pulse Width Modulation (PWM) for stable operation at higher loads.

Features:

  • Ultra-low quiescent current (350nA) for extended battery life
  • Automatic PFM/PWM mode switching for optimized efficiency
  • 100% duty cycle mode for low dropout operation
  • Soft-start and inrush current limiting
  • Power-good output (PG) for system monitoring
  • Forced PWM mode option for noise-sensitive applications
  • Compact DSBGA-12 package for space-constrained designs

This device is designed for battery-powered, always-on applications requiring high efficiency and minimal power loss.
