i3A Series 

## 100W, 9 to 53V Input Non-Isolated Step-Down DC-DC Buck Converter 

https://product.tdk.com/en/power/i3a www.emea.lambda.tdk.com/i3a 

The i3A series of non-isolated DC-DC step-down converters are ideal for creating additional output voltage rails from a single output 12V, 24V or 48V AC-DC or DC-DC power supply including battery sources. The highly efficient i3A series accepts a wide DC input and has a wide output adjustment range in a compact 1/32nd brick footprint. Standard features include output trim, remote sense and negative logic remote On/Off, with an optional power good feature available. 

|**Features**|**Benefits**|
|---|---|
|• Up to 100 W in a 1/32nd brick package|• High Power Density, Less Board Area Needed|
|• High Efficiency Up to 98%|• Longer Battery Life / Less Power Consumed|
|• Wide 3.3 to 16.5V or 5 to 30V Output Adjustment|• One Part Supports Multiple System Voltages|
|• 9 to 53V Input Range|• Can Operate From Different DC Source Voltages Including Batteries|
|• Low Component Count With Minimal External Components|• Low Cost|
|• Minimal Derating Requirements in Low Airflow Environments|• Easy to Cool in End System|
