Product Description

Description
The TPS54320 is a full featured 17-V, 3-A synchronous step-down converter which is optimized for small designs through high efficiency and integrated high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor"s footprint.
Features
• Integrated 57-mΩ / 50-mΩ MOSFETs
• Split Power Rail: 1.6 to 17 V on PVIN
• 200-kHz to 1.2-MHz Switching Frequency
• Synchronizes to External Clock
• 0.8-V Voltage Reference With ±1% Accuracy
• Low 2-µA Shutdown Quiescent Current
• Hiccup Overcurrent Protection
• Monotonic Start-Up into Prebiased Outputs
• –40°C to 150°C Operating Junction Temperature Range
• Pin-to-Pin Compatible With the TPS54620
• Adjustable Slow Start/Power Sequencing
• Power Good Output for Undervoltage and Overvoltage Monitoring
• Adjustable Input Undervoltage Lockout (UVLO)
• Supported by SwitcherPro™ Software Tool
• For SWIFT™ Documentation and SwitcherPro, Visit www.ti.com/swift
Applications
• Broadband, Networking, and Communication Infrastructure
• Automated Test and Medical Equipment
• DSP and FPGA Point-of-Load Applications from 12-V Bus
