The TPS53515 Inductor-On-Top Step-Down Buck Converter reference design enables reduction of X-Y area while enabling >87% efficiency with 2.6W of power loss @12A load and 12mV of output voltage ripple with only 10x22uF ceramic output caps. This power reference design supports a 12V input and a 1.2V output at 12A and switches at 1MHz.
• >87% Efficiency at 12VIN, 1.2Vout, 1MHz
• 2.6W power loss at 11.8W Output Power
• 12mV Output Voltage Ripple at 5A and 1MHz Fsw
• 16mV Output Voltage Overshoot in response to 5A to 10A load step, 2.5A/us
• 17mV Output Voltage Undershoot in response to 10A to 5A load release, 2.5A/us
