TEXAS INSTRUMENTS LM3224MM-ADJ/NOPB. 芯片, 升压转换器, 直流/直流, PWM, MSOP-8, 整卷
The is a step-up PWM DC-to-DC Converter with 0.15R typical/2.45A typical internal switch and a pin selectable operating frequency. With the ability to convert 3.3V to multiple outputs of 8, -8 and 23V, the LM3224 is an ideal part for biasing TFT displays. With the high current switch it is also ideal for driving high current white LEDs for flash applications. An external compensation pin gives the user flexibility in setting frequency compensation, which makes possible the use of small, low ESR ceramic capacitors at the output. An external soft-start pin allows the user to control the amount of inrush current during startup.
