FEATURES  
DESCRIPTION  
3-V to 18-V Input Voltage Range  
High Output Voltage: Up to 38 V  
1.2-A integrated Switch  
The TPS61170 is a monolithic high voltage switching  
regulator with integrated 1.2-A, 40-V power MOSFET.  
It can be configured in several standard  
switching-regulator topologies, including boost and  
SEPIC. The device has a wide input-voltage range to  
support applications with input voltage from multi-cell  
batteries or regulated 5-V, 12-V power rails.  
1.2-MHz Fixed Switching Frequency  
12 V at 300 mA and 24 V at 150 mA from 5-V  
Input (Typical)  
Up to 93% Efficiency  
The TPS61170 uses a 1.2-MHz switching frequency,  
allowing the use low-profile inductors and low-value  
ceramic input and output capacitors. The external  
loop compensation gives the user flexibility to  
optimize loop compensation and transient response.  
The device has built-in protection features, such as  
pulse-by-pulse overcurrent limit, soft start and thermal  
shutdown.  
On-The-Fly Output Voltage Reprogramming  
Skip-Switching Cycle for Output Regulation at  
Light Load  
Built-in Soft Start  
6-Pin, 2 mm × 2 mm QFN Package  
APPLICATIONS  
5-V to 12-V and 24-V, 12-V to 24-V Boost  
Converter  
Buck Boost Regulation Using SEPIC Topology  
ADSL Modems  
The feedback reference voltage of the FB pin is  
1.229V. It can be lowered using a 1-wire digital  
interface (Easyscale™ protocol) through the CTRL  
pin. Alternatively, a pulse width-modulation (PWM)  
signal can be applied to the CTRL pin. The duty cycle  
of the signal reduces the feedback reference voltage  
proportionally.  
The TPS61170 is available in a 6-pin 2 mm × 2 mm  
QFN package, allowing a compact power-supply  
solution.
