PWM Controlled, Step-up DC/DC Converter in Tiny Package Pin Assignments S6 Package (SOT-23-6) 2 1 3 6 4 5 (Marking) CE EXT GND LX VDD FB S9 Package (TSOT-23-6) 2 1 3 6 4 5 (Marking) CE EXT GND LX VDD FB Figure1. Pin Assignment of FP6733 Ordering Information SOT-23-6 Marking Part Number Product Code FP6733S6G AA= TSOT-23-6 Marking Part Number Product Code FP6733S9G aa= Description The FP6733 is a high efficiency PWM DC/DC step-up converter with internal compensated current mode controller. The output voltage is set by using two external resistors. The 550kHz switching frequency minimizes the size of external components. Both internal 1A switch and driver for driving external power device (NMOS or NPN) are provided. The FP6733 starts up below 1V input voltage with 1mA load. Due to built-in automatic PWM/PFM switch-over function, the FP6733 is able to get high efficiency during both light and heavy load. External transistor pin is available to accommodate high output current applications. The FP6733 is available in SOT-23-6 and TSOT-23-6 packages. Features 0.9V (Typ.) Low Start-up Input Voltage at 1mA Load High Switching Frequency at 550kHz Provide Flexibility for Using Internal and External Power Switches Automatic PFM Mode at Light Load Low Ripple and High Efficiency Excellent Line/Load Regulation Chip Enable Control Function Current Limit Protection Thermal Overload Protection Space Saving Packages: SOT-23-6 and TSOT-23-6 Applications PDA MP3 DSC RF Tag Wireless Equipment Portable Equipment FP6733 □□□ G: Green TR: Tape/Reel Package Type S6: SOT-23-6 S9: TSOT-23-6 |
