General Description
The MAX25239/MAX25240 are small, synchronous, buckboost
converters with integrated H-bridge switches. These
ICs provide a fixed-output regulation voltage and an externally
adjustable output voltage in the 3V to 20V range
with an input voltage above, below, or equal to the output
regulation voltage. The IC has typical 8.2A and 10A input
current limit options and can support continuous load currents
up to 6A depending on the input-to-output voltage
ratio and operating frequency. It also has a wide input voltage
range of 2V to 36V.
The MAX25239/MAX25240 have three switching frequency
options: 2.1MHz, 400kHz, and 200kHz. The 2.1MHz
high switching frequency allows small external components
and reduced output ripple, and guarantees no AM
band interference, while the 400kHz or 200kHz switching
frequency offers better efficiency and relieves the power
consumption concern. The SYNC input allows three operation
modes: skip mode with ultra-low quiescent current,
forced fixed-frequency PWM operation, and synchronization
to an external clock. The IC also includes spreadspectrum
frequency modulation to minimize EMI interference.
The MAX25239/MAX25240 feature a power-OK (POK) indicator,
undervoltage lockout, overvoltage protection, cycle-
by-cycle current limit, and thermal shutdown. The ICs
are available in a small, 4.25mm x 4.25mm x 0.75mm,
22-pin FC2QFN package.
