High Power Density 12Vin: 100W Synchronous DC/DC Step-Down Buck Converter with Inductor-On-Top
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: 650KHz6W power loss at 100W Output Power14mV Output Voltage Ripple at 20A output currentOnly 4x100µF output ceramic capacitors27mV Output Voltage Overrshoot in response to 5A to a 10A load increase: 2.5A/µs58.7 °C IC case temperature at 5Vout and 20A output current (100W Output Power)
