BD9300

BD9300/F/FV Regulators 1-channel DC/DC converter controller BD9300/F/FV BD9300/F/FV is an output open collector type of 1-channel DC/DC converter controller. Step-up, step-down and inverting DC/DC converter can be composed. Input voltage range is wide (3.6V to 35V) and this IC can be used widely for various applications. Pin layout is nearly the same as BA9700 and it is easy to replace it. zApplications TV, power supply for liquid crystal TV, Backlight DSC, DVC, Printer, DVD, DVD recorder, Other consumer products zExternal dimensions (Unit : mm) BD9300 19.4 ± 0.3 6.5 ± 0.3 14 8 zFeatures 1) 1-channel PWM control DC/DC converter controller. 2) High voltage input : 3.6 to 35V. 3) Reference voltage accuracy :±1%. 4) Oscillating frequency changeable : 20 to 800kHz. 5) Built-in UVLO (Under voltage lock out) circuit and SCP (Short circuit protection) circuit. 6) Current at stand-by mode : 0µA (typ.) 7) Switching external synchronization available.
