FEATURES  
DESCRIPTION  
Qualified for Automotive Applications  
The TPS61170-Q1 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.  
3-V to 18-V Input Voltage Range  
High Output Voltage: Up to 38 V  
1.2-A integrated Switch  
1.2-MHz Fixed Switching Frequency  
12 V at 300 mA and 24 V at 150 mA from 5-V  
Input (Typical)  
The TPS61170-Q1 operates at a 1.2-MHz switching  
frequency, allowing the use of low-profile inductors  
and low-value ceramic input and output capacitors.  
External loop compensation components give 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.  
Up to 93% Efficiency  
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  
The reference voltage to which the FB pin regulates  
is 1.229V. The reference voltage can be lowered  
using a 1-wire digital interface (Easyscaleprotocol)  
APPLICATIONS  
5-V to 12-V and 24-V, 12-V to 24-V Boost  
Converter  
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.  
Buck Boost Regulation Using SEPIC Topology  
The TPS61170-Q1 is available in a 6-pin 2 mm × 2  
mm QFN package, allowing a compact power-supply  
solution.
