Product Overview

The TPS51123ARGET is a dual-synchronous step down Buck Controller with Out-of-Audio™ operation and targeted for notebook system power supply solutions. It provides 5 and 3.3V LDOs and requires few external components. The TPS51123A supports high-efficiency, fast transient responses and provides a combined power-good signal. Out-of-Audio mode light-load operation enables low acoustic noise at much higher efficiency than conventional forced PWM operation. Adaptive on-time D-CAP control provides convenient and efficient operation. The part operates with supply input voltages ranging from 5.5 to 28V and supports output voltages from 2 to 5.5V.
  • Built-in 1% 2V reference output
  • With/without Out-of-Audio™ mode selectable light-load and PWM-only operation
  • Internal 1.6ms voltage servo soft-start
  • Adaptive on-time control architecture with four selectable frequency setting
  • 4500ppm/°C RDS(on) Current sensing
  • Built-in output discharge
  • Power good output
  • Built-in OVP/UVP/OCP
  • Thermal shutdown (non-latch)
