design features Multiple Power Sources No Problem for 1A, Low Noise
Buck-Boost Converter with 1.8VвЂ“5.5V Input Voltage Range
Genesia Bertelle Users expect their portable devices to operate from a range of power sources including
USB, wall adapters and various types of batteriesвЂ”alkaline, lithium-ion and LiFePO4.
The LTCВ®3536 monolithic synchronous buck-boost converter easily accommodates
a variety of power sources by efficiently operating in both buck and boost modes
from an input voltage range of 1.8V to 5.5V. No complicated topology is required
to accommodate power source inputs above, below or equal to the output. DESIGN VERSATILITY At 3.3V output, a load current of up
to 1A can be supported over the entire
lithium-ion input voltage range; 300m A of
load current is supported when the input
is 1.8V. The 1% accurate output voltage is programmable from 1.8V to
5.5V via an external resistor divider.
The switching frequency of the LTC3536 is
user programmable from 300kHz to 2MHz
via a single external resistor, allowing
the converter to be optimized to meet the
space and efficiency requirements of each 25 transient response regardless of inductor value and output capacitor size. COMPETITIVE BUCK-BOOST
fSW = 1.3MHz 15
5 Depending on the application requirements, a designer can prioritize light load
efficiency or minimize supply noise by
choosing from two operating modes: Burst
ModeВ® operation and PWM operation, …
