Pin Assignment of FR9701 Ordering Information SOT-23-6 Marking Part Number Product Code FR9701S6G t7G TSOT-23-6 Marking Part Number Product Code FR9701S9G t8G Description The FR9701 is a monolithic step-down switch mode converter with a built-in power MOSFET. It achieves 2A output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limit and over temperature protection. The FR9701 requires a minimum number of available standard external components. The FR9701 is available in TSOT-23-6 and SOT-23-6 packages. Features ● 2A Output Current ● 180mΩ Internal Power MOSFET Switch ● Stable with Low ESR Output Ceramic Capacitors ● Up to 92% Efficiency ● Fixed 600KHz Frequency ● Current Mode Operation ● Over-Temperature Protection with Hiccup-Mode ● Cycle-by-Cycle Over Current Protection ● Wide 4.5V to 23V Operating Input Range ● Output Adjustable from 0.805V to 15V ● 10μA Shutdown Current ● Available in TSOT-23-6 and SOT-23-6 Packages Applications ● Battery Charger ● Pre-Regulator for Linear Regulator ● OLPC, Netbook ● Distributed Power System ● WLED Driver FR9701 □□□ G: Green TR: Tape/Reel Package Type S6: SOT-23-6 S9: TSOT-23-6 |
