SLVSAA5A – MAY 2010 – REVISED DECEMBER 2015 TPS61071-Q1 90% Efficient Synchronous Boost Converter With 600-mA Switch
1 Features 3 Description The TPS61071-Q1 device provides a power supply
solution for products powered by lower-voltage DC
rails or a one-cell, two-cell, or three-cell alkaline,
NiCd or NiMH, or one-cell Li-ion or Li-polymer
battery. Output currents can go as high as 75 mA,
while using a single-cell alkaline, and discharge down
to 0.9 V. The device can also generate 5 V at 200 mA
from a 3.3-V rail or a Li-ion battery. The boost
converter is based on a fixed frequency, pulse-widthmodulation (PWM) controller using a synchronous
rectifier to obtain maximum efficiency. The maximum
peak current in the boost switch is limited typically to
a value of 600 mA. 1 Qualified for Automotive Applications
