Description
The MP5423 is a high input voltage power management IC with one buck converter and two LDOs. It is designed for small size & high integration electric-bike control board power management. Integrated buck and LDOs minimize the system components.
The Buck converter adopts peak current mode control, providing 300mA current for load and downstream LDO regulators, while the following LDOs provide 5V and 3.3V regulated power source to system. The current-mode buck converter provides fast transient response and cycle-by-cycle switching current limit. All output voltages are fixed internally with little external components.
The MP5423 features a lot of protection including: VIN ULVO, cycle-by-cycle buck current limit, SCP and OTP.
The MP5423 is available in SOIC8-EP package.
