Description

DESCRIPTION
The TPS51117 is a cost effective, synchronous buck controller for POL voltage regulation in notebook PC applications. The controller is dedicated for Adaptive On-Time D-CAP™ Mode operation that provides ease of use, low external component count, and fast transient response. Auto-skip mode for high efficiency down to the milli-ampere load range, or PWM-only mode for low noise operation is selectable.
FEATURES
• High Efficiency, Low Power Consumption, 4.5-μA Typical Shutdown Current
• Fixed Frequency Emulated On-Time Control, Adjustable from 100 kHz to 550 kHz
• D-CAP™ Mode with 100-ns Load Step Response
• < 1% Initial Reference Accuracy
• Output Voltage Range: 0.75 V to 5.5 V
• Wide Input Voltage Range: 1.8 V to 28 V
• Selectable Auto-Skip/PWM-Only Operation
• Temperature Compensated (4500 ppm/°C)
Low-Side RDS(on) Overcurrent Sensing
• Negative Overcurrent Limit
• Integrated Boost Diode
• Integrated OVP/UVP and Thermal Shutdown
• Power-Good Signal
• Internal 1.2-ms Voltage Softstart
• Integrated Output Discharge (Softstop)
