一,产品概述(General Description) Vmz嘉泰姆

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

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

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

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

2Vmz嘉泰姆	BSTVmz嘉泰姆	Bootstrap pin for top switch. A 0.01uF or larger capacitor should be connected between this pinVmz嘉泰姆 and the SW pin to supply current to the top switch and top switch driver.Vmz嘉泰姆
3Vmz嘉泰姆	VDVmz嘉泰姆	Output of the internal LDO. A capacitor of 2.2uF or larger should be connected at VD to ground.Vmz嘉泰姆
4Vmz嘉泰姆	FBVmz嘉泰姆	Output feedback pin. FB senses the output voltage and is regulated by the control loop to 0.8V.Vmz嘉泰姆 Connect a resistive divider at FB.Vmz嘉泰姆
