    design features Multiple Power Sources No Problem for 1A, Low Noise
    Buck-Boost Converter with 1.8V–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 batteries—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, ...
