FEATURES  
DESCRIPTION  
The TPS55340 is a monolithic non-synchronous  
switching regulator with integrated 5-A, 40-V power  
switch. It can be configured in several standard  
switching-regulator topologies, including boost,  
SEPIC and isolated flyback. The device has a wide  
input voltage range to support applications with input  
voltage from multi-cell batteries or regulated 3.3-V, 5-  
V, 12-V, and 24-V power rails.

Frequency Adjustable from 100kHz to 1.2MHz  
Synchronization Capability to External Clock  
Adjustable Soft-Start Time  
The TPS55340 regulates the output voltage with  
current mode PWM (pulse width modulation) control,  
and has an internal oscillator. The switching  
frequency of PWM is set by either an external resistor  
or by synchronizing to an external clock signal. The  
user can program the switching frequency from 100  
kHz to 1.2 MHz.

The device features  
a programmable soft-start  
QFN-16 (3mmx3mm) and HTSSOP-14  
Packages with PowerPad™  
function to limit inrush current during start-up and has  
other built-in protection features including cycle-by-  
cycle over current limit and thermal shutdown.  
Wide –40°C to 150°C Operating TJ Range  
The TPS55340 is available in a small 3mm x 3mm  
16-pin QFN as well as 14-pin HTSSOP packages  
with PowerPad™ for enhanced thermal performance.

The 5-A, 40-V TPS55340 Boost Converter in the  
HTSSOP-14 package is pin-to-pin compatible with  
the 3-A, 40-V TPS61175 and it extends the maximum  
input voltage from 18 V to 32 V.
