 4I2嘉泰姆

一,产品概述(General Description)   4I2嘉泰姆


     The   CXSD6209A  is a current mode monolithic buck switching regulator. Operating with an input 4I2嘉泰姆

range  of 3.6-40V, the CXSD6209A  delivers 2A of continuous output current with two integrated N-Channel4I2嘉泰姆

 MOSFETs.4I2嘉泰姆
   The CXSD6209A internal synchronous power switches provide high efficiency without4I2嘉泰姆
the use of an external Schottky diode. At light loads, regulators operate in low frequency to4I2嘉泰姆
maintain high efficiency and low output ripple. Current mode control provides tight load transient response 4I2嘉泰姆

and cycle-by-cycle current limit.4I2嘉泰姆
          The CXSD6209A guarantees robustness with short-circuit protection, thermal protection,4I2嘉泰姆
start-up current run-away protection, and input under voltage lockout.4I2嘉泰姆
  The CXSD6209A is available in 8-pin ESOP  package, which provides a compact solution with4I2嘉泰姆
minimal external components. The package has  an exposed pad for low thermal resistance4I2嘉泰姆

SW4I2嘉泰姆

SW is the switching node that supplies power to the output. Connect the output LC filter from SW4I2嘉泰姆
to the output load.4I2嘉泰姆

24I2嘉泰姆

BST4I2嘉泰姆

Bootstrap pin for top switch. A 0.01uF or larger capacitor should be connected between this pin4I2嘉泰姆
and the SW pin to supply current to the top switch and top switch driver.4I2嘉泰姆

34I2嘉泰姆

VD4I2嘉泰姆

Output of the internal LDO. A capacitor of 2.2uF or larger should be connected at VD to ground.4I2嘉泰姆

44I2嘉泰姆

FB4I2嘉泰姆

Output feedback pin. FB senses the output voltage and is regulated by the control loop to 0.8V.4I2嘉泰姆
Connect a resistive divider at FB.4I2嘉泰姆

84I2嘉泰姆

VIN4I2嘉泰姆

Input voltage pin. VIN supplies power to the IC. Connect a 3.6V to 40V supply to VIN and bypass4I2嘉泰姆
VIN to GND with a suitably large capacitor to eliminate noise on the input to the IC.4I2嘉泰姆
