The circuit IPMC7616E-002 of the regulated power supply composed of L296 high current switching power supply chip is shown in Figures a, b, and c, which is a 5-15V, 4A regulated power supply composed of L296 single high current switching power supply chip. The characteristics of L296 single chip high current switching power supply chip are: (1) complete protection function. It is equipped with soft start, overcurrent, overheating, and overvoltage protection. (2) The maximum output current is 4A, the power is 160W, and the output voltage is adjustable between 5.1 and 40V. (3) IPMC7616E-002 with special functions: work prohibition control, synchronous control (ensuring consistent working frequency when multiple outputs are made), reset circuit (providing detection signal of power supply working status), crowbar overvoltage protection circuit (generating a 100mA drive signal when the output voltage exceeds the preset rated voltage by 20% to trigger external protection circuit action). The current expansion circuit form is shown in Figure C.


The IPMC7616E-002 is shown in the figure, which can achieve a larger output power by changing only some components. The circuits R1, L1, D1, C1 to C7 on the left in the figure are conventional common mode filtering and rectification circuits, which obtain a DC voltage of about 300V for use in DC-DC conversion circuits; The rightmost circuits L5, C11, etc. are ordinary LC filtering circuits; IC2, D8, R9, and R10 form a voltage feedback circuit, forming a closed-loop structure to stabilize the power output voltage; The middle part is a DC-DC converter, and the key to noise reduction is to properly process the circuits in this part.
