5V 2A Switching Regulator Circuit Mosfet 2SJ552 LM311 Control

The control of the switching regulated circuit was provided with the lm311, in the tests w-zero3 pda or a similar device was used (I am not entirely sure)

L1 (25uH/2A), R1, R2 (2.2kΩ) This output determines the voltage. Vout = VD1 × (1 + R1/R2) VD1 = 2.5v

C2 (220uF aluminum electrolytic) affects the behavior of the circuit. Low ESR capacitor (like ceramic or OS, laminated parts) ripple can cause more distortion and lower frequency response

D1 (LM385-2.5) 2.5V constant voltage reference source. REF TL431 can be substituted at the cathode and not directly reducing the current shortage of R5 when at the terminal. Need 1kΩ ~ 2.2kΩ.
