一,产品概述(General Description)         LnZ嘉泰姆
        CXSU63038A is a high efficiency synchronous boost regulator that converts LnZ嘉泰姆

down to 2.5V  input and up to 5.5V output voltage. It adopts NMOS for the main LnZ嘉泰姆

switch and PMOS for the synchronous switch. It can disconnect the output fromLnZ嘉泰姆

 input during the shutdown mode.. It integrates 6A power MOSFET and can LnZ嘉泰姆

output 5V 2.5A with Li-Battery input.LnZ嘉泰姆

七,功能概述LnZ嘉泰姆

The controller circuit of the device is based on a fixed frequency multiple feedforwardLnZ嘉泰姆
controller topology. Input voltage, output voltage, and voltage drop on the NMOS switch areLnZ嘉泰姆
monitored and forwarded to the regulator. So changes in the operating conditions of theLnZ嘉泰姆
converter directly affect the duty cycle and must not take the indirect and slow way throughLnZ嘉泰姆
the control loop and the error amplifier. The control loop, determined by the error amplifier,LnZ嘉泰姆
only has to handle small signal errors. The input for it is the feedback voltage on the FB pin,LnZ嘉泰姆
the voltage on the internal resistor divider. It is compared with the internal reference voltageLnZ嘉泰姆
to generate an accurate and stable output voltage.LnZ嘉泰姆
The peak current of the NMOS switch is also sensed to limit the maximum current flowingLnZ嘉泰姆
through the switch and the inductor. The typical peak current limit is set to exceed 6A. AnLnZ嘉泰姆
internal temperature sensor prevents the device from getting overheated in case ofLnZ嘉泰姆
excessive power dissipation.LnZ嘉泰姆
