Description  
Application Information  
1
SW  
Switching Node  
Power switching node. Connect to the inductor,  
bootstrap capacitor, and free-wheeling diode.  
2
3
BST  
RCL  
Boost Boot–strap capacitor input  
An external capacitor is required between the BST  
and the SW pins. A 0.01µF ceramic capacitor is  
recommended.  
Current Limit OFF time programming pin  
A resistor between this pin and RTN sets the off-time  
when current limit is detected. The off-time is preset  
to 17 µs if FB = 0V .

RTN  
FB  
Circuit Ground  
Feedback Signal from Regulated Output  
This pin is connected to the inverting input of the  
internal regulation comparator. The regulation  
threshold is 2.5V.  
6
7
RON/SD On-time set pin  
A resistor between this pin and VIN sets the switch on-  
time as a function of Vin. The minimum recommended  
on-time is 300ns at the maximum input voltage.  
VCC  
Output from the internal high voltage bias regulator. If an auxiliary voltage is available to raise the voltage  
on this pin above the regulation setpoint (7V), the  
internal series pass regulator will shutdown, reducing  
the IC power dissipation. Do not exceed 14V. This  
output provides gate drive power for the internal Buck  
switch. An internal diode is provided between this pin  
and the BST pin. A local 0.1uF decoupling capacitor  
is recommended.

Input supply voltage  
Recommended operating range: 9V to 42V.  
Exposed pad, underside of the LLP package option Exposed metal pad on the LLP package underside. It  
is recommended to connect this pad to the PC board  
ground plane to aid in heat dissipation.
