By this system, when load current changes suddenly, it responds at high speed and minimizes the changes of output voltage. Since it is possible to use capacitors with small capacitance and it is unnecessary to add external parts for system phase compensation, this IC realizes downsizing of set and reducing in the number of external parts. Output voltage is adjustable by user. Maximum current is 10 A. Condition : VIN = 12 V, VOUT Setting = 1.05 V, Switching Frequency = 430 kHz, Low Power Mode / Normal Mode, LO = 1 µH, CO = 88 µF (22 µF x 4) #Including V5 current VFB V5 EN PGOOD BST LX PGND AGND SS AVIN PVIN V5 AVIN NN30332A PVIN VOUT VOUT = 1.05 V 1 µH 100 k 22 µF 4 0.1 µF 27 k 36 k 3.3 nF V5 10 A Synchronous DC-DC Step down Regulator with low quiescent power mode (VIN = 4.5 V to 24 V, VOUT = 0.75 V to 3.6 V) http://www.semicon.panasonic.co.jp/en/ SIMPLIFIED APPLICATION Note : The application circuit is an example.
