## 200W, 9 to 36V or 18 to 75 V Input Non-Isolated 1 x 1” DC-DC Buck-Boost Converters 

The i1C series are non-isolated buck-boost DC-DC converters that delivers up to 200W in a  compact and familiar industry standard 1 x 1 inch footprint. Operating from either a 9-36V or 18-75V input, it comes with a wide adjustable output of 9.6 to 28V that can support multiple system load voltages, minimizing part number variations. Encased in a 5-sided metal case that supports -40 to 120°C case temperature operation along with its remarkable 98% efficiency, the i1C series provides a higher power migration path in applications where space is at a premium. 

|**Features**|**Benefits**|
|---|---|
|• Up to 200W in a 1 x 1 inch Industry Footprint|• High Power Density, Less Board Area Needed|
|• Encapsulated in a 5-sided metal case|• Improves EMI|

Notes 

(1) Typical specification unless otherwise indicated. See website for detailed product specifcations. 

(2) Observe maximum power limit. Allowable output current varies with input voltage. 

(3) Measured with one 330 μF electrolytic and 22 μF ceramic capacitors, BW = 20MHz. 

(4) Contact technical support for very low ESR capacitor banks or if higher capacitance is required.

## **Typical Application Circuit** 

## Recommendation 

1. Cin and Cout MLCC should be connected to the i1C module as close as possible to reject high frequency noise. 

2. Connect Vin(-) and Vout(-) to copper ground plane underneath the i1C module. 

3. TRIM resistors Rup or Rdn should be connected to the i1C module as close as possible.
