Product Description

DESCRIPTION
The TPS54339 is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54339 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54339 uses the D-CAP2™ mode control that provides a fast transient response with no external compensation components. The TPS54339 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra low ESR ceramic capacitors.
FEATURES
• D-CAP2™ Mode Enables Fast Transient Response
• Low Output Ripple and Allows Ceramic Output Capacitor
• Wide VIN Input Voltage Range: 4.5 V to 23 V
• Output Voltage Range: 0.76 V to 7 V
• Highly Efficient Integrated FETs Optimized for Lower Duty Cycle Applications
– 140 mΩ (High Side) and 70 mΩ (Low Side)
• High Efficiency, less than 10 μA at shutdown
• High Initial Bandgap Reference Accuracy
• Adjustable Soft Start
• Pre-Biased Soft Start
• 600-kHz Switching Frequency (fSW)
• Cycle By Cycle Over Current Limit
APPLICATIONS
• Wide Range of Applications for Low Voltage System
– Digital TV Power Supply
– High Definition Blu-ray Disc™ Players
– Networking Home Terminal
– Digital Set Top Box (STB)
