IR3621MPBF Overview
This switching controller fits most application requirements since it is packaged in a 32-VFQFN Exposed Pad package. It is sufficient to generate 2 outputs with this dc motor controller. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 5.5V~14.5V voltage are supplied and operated. Worked in a -40°C~125°C TJ dc switcher before. This switching controller can switch at 200kHz~500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control, Power Good, Soft Start. Searching "IR3621MPBF" will return other relevant dc to dc converter ics. There are only 32 pins on switching converter. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. It is estimated that this dc regulatorhas a maximum frequency of 345kHz. There is 500kHz frequency setting on the switching controller. A temperature -40°C lower than -40°C should be maintained. Running the machine at 125°C is ideal. You can set the input voltage to 20V for nominal working status. There is 32-MLPQ (5x5) dc dc controller package associated with this part. Voltage maximum is rated 14.5V.
