一,产品概述(General Description)   bxG嘉泰姆

    The CXSD61036 is high efficiency synchronous,PWM step-downbxG嘉泰姆
DC/DC converters working under an input voltagebxG嘉泰姆
range of 2.5V to 5.5V. This feature makes the CXSD61036 suitablebxG嘉泰姆
for single Li-lon battery-powered applications.100% duty cyclebxG嘉泰姆
capability extends battery life in portable devices, while the quiescentbxG嘉泰姆
current is 200 A with no load, and drops to < 1 A in shutdown.bxG嘉泰姆
       The internal synchronous switch is  desired to increase efficiencybxG嘉泰姆
without an external Schottky diode. The 1.4 MHz fixed switchingbxG嘉泰姆
frequency allows the using of tiny,low profile inductors and ceramicbxG嘉泰姆
capacitors,which minimized overall solution footprintbxG嘉泰姆
        The CXSD61036 converters are available in the industry standardbxG嘉泰姆

INDUCTOR SELECTIONbxG嘉泰姆

For most applications, the value of the inductor will fall in the range of 1μH to 4.7μH. Its value isbxG嘉泰姆
chosen based on the desired ripple current. Large value inductors lower ripple current and smallbxG嘉泰姆
value inductors result in higher ripple currents. Higher VIN or VOUT also increases the ripplebxG嘉泰姆

current as shown in equation 1. A reasonable starting point for setting ripple current is
IL =240mA (40% of 600mA).bxG嘉泰姆
The DC current rating of the inductor should be at least equal to the maximum load current plusbxG嘉泰姆
half the ripple current to prevent core saturation. Thus, a 720mA rated inductor should bebxG嘉泰姆
enough for most applications (600mA + 120mA). For better efficiency, choose a low DC-resistancebxG嘉泰姆
inductor.bxG嘉泰姆
Different core materials and shapes will change the size/current and price/current relationship ofbxG嘉泰姆
an inductor. Toroid or shielded pot cores in ferrite or permalloy materials are small and don’tbxG嘉泰姆
radiate much energy, but generally cost more than powdered iron core inductors with similarbxG嘉泰姆
electrical characteristics. The choice of which style inductor to use often depends more on thebxG嘉泰姆

price vs size requirements and any radiated field/EMI requirements than on what the CXSD61036bxG嘉泰姆

requires to operate. Table 1 shows some typical surface mount inductors that work well inbxG嘉泰姆
