一,产品概述(General Description) 7iU嘉泰姆
The CXSD6209A is a current mode monolithic buck switching regulator. Operating with an input 7iU嘉泰姆
range of 3.6-40V, the CXSD6209A delivers 2A of continuous output current with two integrated N-Channel7iU嘉泰姆
MOSFETs.7iU嘉泰姆
The CXSD6209A internal synchronous power switches provide high efficiency without7iU嘉泰姆
the use of an external Schottky diode. At light loads, regulators operate in low frequency to7iU嘉泰姆
maintain high efficiency and low output ripple. Current mode control provides tight load transient response 7iU嘉泰姆
and cycle-by-cycle current limit.7iU嘉泰姆
The CXSD6209A guarantees robustness with short-circuit protection, thermal protection,7iU嘉泰姆
start-up current run-away protection, and input under voltage lockout.7iU嘉泰姆
The CXSD6209A is available in 8-pin ESOP package, which provides a compact solution with7iU嘉泰姆
minimal external components. The package has an exposed pad for low thermal resistance7iU嘉泰姆

Description7iU嘉泰姆 |
|
17iU嘉泰姆 |
SW7iU嘉泰姆 |
SW is the switching node that supplies power to the output. Connect the output LC filter from SW7iU嘉泰姆
to the output load.7iU嘉泰姆 |
|
27iU嘉泰姆 |
BST7iU嘉泰姆 |
Bootstrap pin for top switch. A 0.01uF or larger capacitor should be connected between this pin7iU嘉泰姆
and the SW pin to supply current to the top switch and top switch driver.7iU嘉泰姆 |
|
37iU嘉泰姆 |
VD7iU嘉泰姆 |
Output of the internal LDO. A capacitor of 2.2uF or larger should be connected at VD to ground.7iU嘉泰姆 |
|
47iU嘉泰姆 |
FB7iU嘉泰姆 |
Output feedback pin. FB senses the output voltage and is regulated by the control loop to 0.8V.7iU嘉泰姆
Connect a resistive divider at FB.7iU嘉泰姆 |

EN7iU嘉泰姆 |
Drive EN pin high to turn on the regulator and low to turn off the regulator.7iU嘉泰姆 |
|
87iU嘉泰姆 |
VIN7iU嘉泰姆 |
Input voltage pin. VIN supplies power to the IC. Connect a 3.6V to 40V supply to VIN and bypass7iU嘉泰姆
VIN to GND with a suitably large capacitor to eliminate noise on the input to the IC.7iU嘉泰姆 |
