一,产品概述(General Description) RYi嘉泰姆
The CXSD6209A is a current mode monolithic buck switching regulator. Operating with an input RYi嘉泰姆
range of 3.6-40V, the CXSD6209A delivers 2A of continuous output current with two integrated N-ChannelRYi嘉泰姆
MOSFETs.RYi嘉泰姆
The CXSD6209A internal synchronous power switches provide high efficiency withoutRYi嘉泰姆
the use of an external Schottky diode. At light loads, regulators operate in low frequency toRYi嘉泰姆
maintain high efficiency and low output ripple. Current mode control provides tight load transient response RYi嘉泰姆
and cycle-by-cycle current limit.RYi嘉泰姆
The CXSD6209A guarantees robustness with short-circuit protection, thermal protection,RYi嘉泰姆
start-up current run-away protection, and input under voltage lockout.RYi嘉泰姆
The CXSD6209A is available in 8-pin ESOP package, which provides a compact solution withRYi嘉泰姆
minimal external components. The package has an exposed pad for low thermal resistanceRYi嘉泰姆

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