IZ1583
General Description The IZ1583 is a step-down regulator with a built in internal power MOSFET. The IC provide 3A continuous output current over a wide supply voltage range. The IC can be used as distributed power source, battery charger, pre-regulator for linear regulators. Features • Wide supply voltage range 4,75 … 23 V. • Wide operating temperature range -40 … +85 oC. • Active mode consumption current (max.) 1,2 mA . • Chip dimensions 1,91 × 1,42 mm. • ICs are available for shipment in chip form on unsawn wafers • Functionality IC performs driving of power built in MOSFET switch, quantity of energy transferred to load is regulated by means of MOSFET on-time (pulse-width modulation). So ouput voltage practically do not depends from load.
