+
+## Description
+
++48Vin DC/DC Buck converter module, with added input protection circuitry.
+
+Input protections: 
+    - Reverse voltage
+    - Transient voltage protection
+
+Outputi protections: 
+    - Overcurrent protection
+
+Opperation protections: 
+    - Under/Over Voltage
+    - Thermal Shutdown    
+
+
+## Theory of opperation
+ - Vin      : 5[V] to 50[V]
+ - Vout     : 0.8[V] to 45[V] 
+ - Iout     : 3[A] Max
+ - Eff.     : 85%-95%
+ - Freq     : 300[Khz] to 2.8[MHz]
+ - θJA      : 50 °C/W
+ - SoftStar : Yes
