In these applications we wanted to share the high powered circuits by adding MOSFETs to raise the LM2575, LM2575 outgoing current. Generally we are wondering about power amplification in such regulator integrations.
Note: I do not share projects that do not have pictures of the person who made them, but these applications are worth trying with the exception of the higher power 🙂
LM2575 5A 2V-30 ADJUSTABLE DC DC CONVERTER
First application 2V … Adjustable power supply circuit with adjustable 5V amperage switchable between 30V .. Circuit can be realized with LM2575-ADJ writer LM2575 adjusted (ADJ version) 16 pin DIP jacket used PCB can use LM2575-ADJ TO220 sheath prepared accordingly .. Mosfet P Channel IRF9540 ( RDSON, P-channel MOSFET must be used due to gate voltage losses ) It is necessary that the 100uH coil is strong enough to meet the output current
If the fixed output LM2575-5 LM2575-3.3 is used, the potentiometer will be canceled and the SA write point will be short-circuited
LM2576 8A 5V DC DC STEP-DOWN
In this application, the LM2576-5 used output voltage is 5v power, 8 amper power, voltage difference compared to the same integrated model used in two application schemes
