一,  产品概述(General Description)      4jE嘉泰姆
直线4jE嘉泰姆
   The CXSD62232 is a monolithic synchronous buck regulator. The device integrates two 90mΩ MOSFETs, and provides2.2A of continuous loadcurrent over a wide input voltage of 4.75V 4jE嘉泰姆
to 37V.Current mode control provides fast transient response and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn-on, and inshuJTMTown mode 4jE嘉泰姆
the supply current drops to 1μA.This device, available in an SOP8-PP package, provides a verycompact solution with minimal external components4jE嘉泰姆

Pin Name4jE嘉泰姆

Description4jE嘉泰姆

14jE嘉泰姆

BS4jE嘉泰姆

High-Side Gate Drive Boost Input. BS supplies the drive for the high-side N-Channel4jE嘉泰姆
MOSFET switch. Connect a 0.01μF or greater capacitor from SW to BS to power the4jE嘉泰姆
high side switch.4jE嘉泰姆

24jE嘉泰姆

IN4jE嘉泰姆

Power Input. IN supplies the power to the IC, as well as the step-down converter4jE嘉泰姆
switches. Drive IN with a 4.75V to 32V power source. Bypass IN to GND with a4jE嘉泰姆
suitably large capacitor to eliminate noise on the input to the IC. See Input Capacitor.4jE嘉泰姆

34jE嘉泰姆

SW4jE嘉泰姆

Power Switching Output. SW is the switching node that supplies power to the output.4jE嘉泰姆
Connect the output LC filter from SW to the output load. Note that a capacitor is4jE嘉泰姆
required from SW to BS to power the high-side switch.4jE嘉泰姆

44jE嘉泰姆

GND4jE嘉泰姆

Ground.4jE嘉泰姆

54jE嘉泰姆

FB4jE嘉泰姆

Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB4jE嘉泰姆
with a resistive voltage divider from the output voltage. The feedback threshold4jE嘉泰姆
is 0.923V. See Setting the Output Voltage.4jE嘉泰姆

64jE嘉泰姆

COMP4jE嘉泰姆

Compensation Node. COMP is used to compensate the regulation control loop.4jE嘉泰姆
Connect a series RC network from COMP to GND to compensate the regulation4jE嘉泰姆
control loop. In some cases, an additional capacitor from COMP to GND is4jE嘉泰姆
required. See Compensation Components.4jE嘉泰姆

74jE嘉泰姆

EN4jE嘉泰姆

Enable Input. EN is a digital input that turns the regulator on or off. Drive EN high to4jE嘉泰姆
turn on the regulator, drive it low to turn it off. Pull up with 100kΩ resistor for4jE嘉泰姆
automatic startup.4jE嘉泰姆

84jE嘉泰姆

SS4jE嘉泰姆

Soft-Start Control Input. SS controls the soft start period. Connect a capacitor from SS4jE嘉泰姆
to GND to set the soft-start period. A 0.1μF capacitor sets the soft-start period to 15ms.4jE嘉泰姆
To disable the soft-start feature, leave SS unconnected.4jE嘉泰姆
