Product Description

DESCRIPTION
The TPS5420 is a high-output-current PWM converter that integrates a low resistance high side N-channel MOSFET. Included on the substrate with the listed features is a high performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 5.5 V; an internally set slow-start circuit to limit inrush currents; and a voltage feed-forward circuit to improve the transient response.
FEATURES
• Wide Input Voltage Range: 5.5 V to 36 V
• Up to 2-A Continuous (3-A Peak) Output Current
• High Efficiency up to 95% Enabled by 110-mΩ Integrated MOSFET Switch
• Wide Output Voltage Range: Adjustable Down to 1.22 V with 1.5% Initial Accuracy
• Internal Compensation Minimizes External Parts Count
• Fixed 500-kHz Switching Frequency for Small Filter Size
• Improved Line Regulation and Transient Response by Input Voltage Feed Forward
• System Protected by Over Current Limiting, Over Voltage Protection and Thermal Shutdown
• –40°C to 125°C Operating Junction Temperature Range
• Available in Small 8-Pin SOIC Package
APPLICATIONS
• Consumer: Set-top Box, DVD, LCD Displays
• Industrial and Car Audio Power Supplies
• Battery Chargers, High Power LED Supply
• 12-V/24-V Distributed Power Systems
