Figure 22 is a DC converter circuit constituted by the BIC1222. BIC1222 has two synchronous rectifier power MOSFET, the control circuit, over-current protection circuit and thermal protection circuit module. It has on and off function. The circuit's input voltage is +8 ~ +20 V, output voltage is + 2.5 ~ +5.3 V, output current is 5A. The output voltage is setted by external resistors R1 and R2 in the range of +2.5 ~ +12 V. Output voltage U. = [2.45V (R1 +2 R)] / R2. In the circuit, R2 = 2.2KΩ, U. = 2.5V, R1 = 47Ω; U. 3.3V, R1 = 770Ω; U. 5.0V, R1 = 2.3KΩ.
