What is the action that emperor helps electric current of small static state rise step-down converter?

The function that consumes kind of electron product nowadays and appearance abound diversity gradually, use setting is extensive, this asks to increase increasingly to the function of semiconductor device. The crucial index such as electric current of the power density to power source product, efficiency, static state put forward earphone of burgeoning terminal TWS and miniaturization of mobile phone dimension to be challenged newly. Holy state microelectronics is brand-new SGM62110 of litre of step-down DC/DC converter that roll out, devote oneself to to solve consume kind of electron product to be opposite the high demand of power source parts of an apparatus.

SGM62110 in WLCSP-2.21 × 1.40-15B encloses implementation 2.5A laden ability, need parts of an apparatus of periphery of 4 0603 dimension to be able to achieve integral solution only. Be as high as the peak value efficiency of 95% , and when electric current of static state of 18 μ A promotes batteries the use of power supply application substantially, grow. The function with tie-in and substantial agreement of compositive communication of high speed I2C configures register to realize the intelligence of terminal product effectively to change. SGM62110 is compositive flow too, press too, the protective mechanism such as too lukewarm, short circuit, promoted the rash club of the product gender and reliability substantially.

SGM62110 DVS function

SG Micro Corp

Function of DVS (Dynamic Voltage Scaling) promotes a system effectively the overall efficiency below different job mode. VSEL brings a foot to cooperate [VOUTx] register allows chip to be in the job is medium dynamic adjustment to output voltage, satisfy a system to be mixed in mode of low power comsumption thereby be fully loaded with efficiency of tall changeover of the implementation below the job. Additional, the DVS function of SGM62110 can support low to 25mV pressure regulating the pace is entered and pressure regulating slope control, realize essence of life to allow to be changed with flowing voltage thereby.

The DVS below PFM mode

The DVS below FPWM mode

In the DVS below FPWM mode, SGM62110 provided function of RPWM (Ramp PWM) , below laden without output condition, implementation outputs voltage from go to lowly flowing adjustment high, in order to facilitate systematic sequential is controlled.
