Description

The TPS53355 Inductor-On-Top step-down buck converter design enables high power density through reduction of X-Y PCB area by placing the output inductor on top of the IC and results in 92% minimum efficiency for 66W and 100W output power designs (3.3V and 5V output)  requiring only 4x100µF ceramic output caps.

Features
  • 94% Efficiency at 12VIN, 5Vout,20A output current, 650KHz
  • 6W power loss at 100W Output Power
  • 14mV Output Voltage Ripple at 20A output current
  • Only 4x100µF output ceramic capacitors
  • 27mV Output Voltage Overrshoot in response to 5A to a 10A load increase, 2.5A/µs
  • 58.7°C IC case temperature at 5Vout and 20A output current (100W Output Power)
