一,产品概述(General Description)         C0v嘉泰姆
         The CXSU63035 is a compact, high-efficiency, synchronous step-up converter with power MOSFETintegrated for a single-cell Li-ion/polymer battery. This converterC0v嘉泰姆
consumes only 100uA quiescent current when no switching. When current load is light, this converter enters burst mode to obtain high efficiency. When current load isC0v嘉泰姆
heavy enough, it enters fixed-frequency PWM mode. It adopts peak current mode for fast transient response with internal compensation. This converter contains  cycle-by-cycle current limiting and short protection circuit. It is suitable for iPad-like computers, smart phones and portable handheld devices. The device is packed in ESOP8 package.C0v嘉泰姆

UnderVoltage LockoutC0v嘉泰姆

An under voltage lockout function prevents device start-up if the supply voltage on VBAT is lower thanC0v嘉泰姆
approximately 2.8V. When in operation and the battery is being discharged, the device automatically enters theC0v嘉泰姆
shutdown mode if the voltage on VBAT drops below approximately 2.5V. This under voltage lockout function isC0v嘉泰姆
implemented in order to prevent the malfunctioning of the converter. C0v嘉泰姆
SoftStartC0v嘉泰姆
When the device enables the internal start-up cycle, it starts with the first step, the precharge phase. DuringC0v嘉泰姆
precharge, the rectifying switch is turned on until the output capacitor is charged to a value close to the inputC0v嘉泰姆
voltage. The rectifying switch current is limited in that phase. This also limits the output current underC0v嘉泰姆
short-circuit conditions at the output. After charging the output capacitor to the input voltage the device startsC0v嘉泰姆
switching.C0v嘉泰姆

Application InformationC0v嘉泰姆

Because of the high integration in the CXSU63035, the application circuit based on this regulator IC is ratherC0v嘉泰姆
simple. Only input capacitor CIN, output capacitor COUT, inductor L and feedback resistors (R1 and R2) need toC0v嘉泰姆
be selected for the targeted applications specifications.C0v嘉泰姆
Feedback resistor dividers R1 and R2:C0v嘉泰姆
Choose R1 and R2 to program the proper output voltage. To minimize the power consumption under light loads,C0v嘉泰姆
it is desirable to choose large resistance values for both R1 and R 2. A value of between 10k and 1M isC0v嘉泰姆
recommended for both resistors. If R1=200k is chosen, then R2 can be calculated to be:C0v嘉泰姆
R2 = (R1×0.6V)/(VOUT - 0.6V)C0v嘉泰姆
Input capacitor CIN:C0v嘉泰姆
To minimize the potential noise problem, place a typical X5R or better grade ceramic capacitor really close toC0v嘉泰姆
the IN and GND pins. Care should be taken to minimize the loop area formed by CIN, and IN/GND pins. In thisC0v嘉泰姆
case a 10uF low ESR ceramic is recommended.C0v嘉泰姆
Output capacitor COUT:C0v嘉泰姆
The output capacitor is selected to handle the output ripple noise requirements. Both steady state ripple andC0v嘉泰姆
transient requirements must be taken into consideration when selecting this capacitor. For the best performance,C0v嘉泰姆
it is recommended to use X5R or better grade ceramic capacitor with 10V rating and more than two pcs 22uFC0v嘉泰姆
