Introduction
TPS40077EVM-001 is designed to use a 12-V (8 V-to-16 V) bus to produce a high current, regulated
1.8-V output at up to 10 A of load current. The TPS40077EVM-001 demonstrates the use of the
TPS40077 in a typical 12-V bus to low-voltage application, while providing a number of test points to
evaluate the performance of the TPS40077. The EVM can be modified to support output voltages from 0.9
V to 3.3 V by changing a single resistor.
• Non-isolated, medium-current point-of-load and low-voltage bus converters.
• Networking equipment
• Telecommunications equipment
• DC-power distributed systems
• 8 V–16 V input range
• 1.8-V fixed output, adjustable with single resistor
• 10-A DC steady-state output current
• 300-kHz switching frequency
• Single main switch N-channel MOSFET and single synchronous rectifier N-channel MOSFET
• Double-sided PCB with all components on top side
• Active converter uses less than 2.4 square inches – 1.0" × 2.4"
• Convenient test points for probing critical waveforms and non-invasive loop response testing
