司网站查到相关介绍）如果输出电流需要2.4a ，可以看fp6276b ，如果输出电流需要1a 及以下，可以看ps7516 。        the fp6277 is a current mode boost dc dc converter with pwm/psm control. itspwm circuitry with built-in 30m 937 high side switch and 30m 937 low side switch make this regulator highly power efficient. the internal compensation network also minimizes external component counts to only 6. an internal 0.6v voltage is connected to error amplifier the non-inverting input as precision reference voltage. built-in soft-start function can reduce the inrush current. features 特

）日益显得重要，成为业界开始关注的焦点。  10-bit dac 120ma vcm driver  with i2c interface  （fp5510 ）the fp5510 is a single 10-bit dac with 120maoutput current voice coil motor vcm driver with an  i2c-compatible serial interface that operates at clock  rates up to 400khz. itssupply operates from 2.3v to  3.6v. the fp5510 incorporates with a power-on reset  circuit power-down function. power-on reset circuit  ensure when supply power up dac output is to 0v  until valid write bit value takes place. in power down  mode the supply current is about 1 956 a. the fp5510 is designed for auto focus operation  includes digital camera
