The TPS53355 Inductor-On-Top step-down buck converter design enables high power density through reduction of X-Y PCB area and results in >86% efficiency with only 1.8W of power loss and 6mV of output voltage ripple requiring only 5x100uF ceramic output caps.
• >86% Efficiency at 12VIN, 1Vout, 650KHz
• 1.8W power loss at 12.6W Output Power
• 6mV Output Voltage Ripple
• 2.4mV Output Voltage Overshoot in response to 3A to 6A load step, 2.5A/us
• 2.2mV Output Voltage Undershoot in response to 6A to 3A load release, 2.5A/us
• 39 total components including IC
