FP5207 original internal design and development software: high power buck-boost application

FP5207 is a non-synchronous boost control IC. It controls the external NMOS through the EXT Pin. It has a low input startup voltage of 2.8V and a wide operating voltage of 5V~24V. It is suitable for single-cell lithium battery 3V~4.2V applications. Connect Vout to the HVDD Pin. It has a precise feedback voltage of 1.2V, built-in soft start, and the operating frequency is adjusted by an external resistor. For over-current protection, it detects the inductor peak current. The detection resistor Rcs is connected between the switch NMOS Source terminal and ground.
