300W, 9 to 53V or 9 to 36V Input Non-Isolated Buck-Boost DC-DC Converter 

The i7C series of non-isolated step-up / step-down converters are ideal for generating additional DC output voltage rails up to 300 W from a single output 12V, 24V or 48V AC-DC power supply.  The highly efficient i7C series accepts a very wide DC input and has a wide output adjustment range.  Three mechanical configurations are available; low profile open frame, baseplate construction for conduction cooling, or integral heat sink for convection or forced air cooling.  Full feature(*) options are available including output current monitoring (Imon), switching frequency synchronization (Sync) and power good (PG) or output current limit adjust (Itrim). 

|**Features**|**Benefits**|
|---|---|
|• Up to 300W in a 1/16th Brick Pin-Out|• High Power Density, Less Board Area Needed|
|• High Efficiency - Up to 97%|• Longer Battery Life / Low Power Consumed|
|• Wide 5 to 28V, 8 to 24V or 9.6 to 48V Output Adjustment|• One Part Supports Multiple System Voltages|
|• Wide 9 to 36V or 9 to 53V Input Range|• Compatible With a Wide Range of DC Source Voltages|
|• Low Component Count With Minimal External Components|• Low Cost|
|• Low Airflow With Minimal Derating Requirements|• Easy To Cool In End System|

Recommendations: 

1.   Cin/Cout MLCC should be connected to the i7C module as close as possible in order to reject high-frequency noise. 

2.   Connect Vin(-) and Vout(-) to copper ground plane underneath the i7C module. 

3.   TRIM resistor “Rup” should be connected to the i7C module as close as possible. 

4.   SYNC must be connected to GND when not in use. 

5.   External R-C filter may need for Current Monitor. 

6.   Current limit TRIM resistor “Ritrim” should be connected to the i7C module as close as possible.
