一,产品概述(General Description) deu嘉泰姆

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

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

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

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

1deu嘉泰姆	SWdeu嘉泰姆	SW is the switching node that supplies power to the output. Connect the output LC filter from SWdeu嘉泰姆 to the output load.deu嘉泰姆
2deu嘉泰姆	BSTdeu嘉泰姆	Bootstrap pin for top switch. A 0.01uF or larger capacitor should be connected between this pindeu嘉泰姆 and the SW pin to supply current to the top switch and top switch driver.deu嘉泰姆
3deu嘉泰姆	VDdeu嘉泰姆	Output of the internal LDO. A capacitor of 2.2uF or larger should be connected at VD to ground.deu嘉泰姆
4deu嘉泰姆	FBdeu嘉泰姆	Output feedback pin. FB senses the output voltage and is regulated by the control loop to 0.8V.deu嘉泰姆 Connect a resistive divider at FB.deu嘉泰姆
