TECHNICAL NOTE Single-chip Type with Built-in FET Switching Regulator Series 2-output High-efficiency Step-down Switching Regulators with Built-in Power MOSFET BD9302FP Description The BD9302FP is a 2-channel step-down switching regulator controller with a 2.5-MHz, 2-A power switch and available for 2.5-MHz high speed switching operation, which facilitates settings of switching frequency with external resistance, supporting for a wide input voltage range of 6 to 18 V. Furthermore, due to a low reference voltage of 0.6 V, this BD9302FP is an L/C best suited to high-voltage input/low-voltage output applications, for example, to step down a voltage from 12 V to 1.2 V. Features 1) A wide input voltage range of 6 V to 18 V 2) Easy switching frequency setting in the range of 200 k to 2.5 MHz. 3) Two built-in power switches of 0.4 , 2 A. 4) 180 phase shift 5) Built-in Under Voltage Lock Out circuit 6) Built-in overcurrent protection circuit 7) Built-in Thermal Shutdown circuit Use Power supply for DPS requiring two power sources ADSL modem/plasma display Audio devices Dec. 2008Absolute maximum ratings (Ta=25C) Item Symbol Rating Unit Power supply voltage Vcc 20 V Power dissipation Pd 1450* mW Operating temperature Topr -40 ~ +85 C Storage temperature Tstg -55 ~ +150 C Output current Io 2** A Maximum junction temperature Tjmax 150 C * Should be derated by 11.6 mW/C at Ta=25C or more.
