一,产品概述(General Description)   3tx嘉泰姆

     The   CXSD61052  is a current mode monolithic buck switching regulator. Operating with an input 3tx嘉泰姆

range  of 3.6-40V, the CXSD61052  delivers 2A of continuous output current with two integrated N-Channel3tx嘉泰姆

 MOSFETs.3tx嘉泰姆
   The CXSD61052 internal synchronous power switches provide high efficiency without3tx嘉泰姆
the use of an external Schottky diode. At light loads, regulators operate in low frequency to3tx嘉泰姆
maintain high efficiency and low output ripple. Current mode control provides tight load transient response 3tx嘉泰姆

and cycle-by-cycle current limit.3tx嘉泰姆
          The CXSD61052 guarantees robustness with short-circuit protection, thermal protection,3tx嘉泰姆
start-up current run-away protection, and input under voltage lockout.3tx嘉泰姆
  The CXSD61052 is available in 8-pin ESOP  package, which provides a compact solution with3tx嘉泰姆
minimal external components. The package has  an exposed pad for low thermal resistance3tx嘉泰姆

SW3tx嘉泰姆

SW is the switching node that supplies power to the output. Connect the output LC filter from SW3tx嘉泰姆
to the output load.3tx嘉泰姆

23tx嘉泰姆

BST3tx嘉泰姆

Bootstrap pin for top switch. A 0.01uF or larger capacitor should be connected between this pin3tx嘉泰姆
and the SW pin to supply current to the top switch and top switch driver.3tx嘉泰姆

33tx嘉泰姆

VD3tx嘉泰姆

Output of the internal LDO. A capacitor of 2.2uF or larger should be connected at VD to ground.3tx嘉泰姆

43tx嘉泰姆

FB3tx嘉泰姆

Output feedback pin. FB senses the output voltage and is regulated by the control loop to 0.8V.3tx嘉泰姆
Connect a resistive divider at FB.3tx嘉泰姆

VIN3tx嘉泰姆

Input voltage pin. VIN supplies power to the IC. Connect a 3.6V to 40V supply to VIN and bypass3tx嘉泰姆
VIN to GND with a suitably large capacitor to eliminate noise on the input to the IC.3tx嘉泰姆
