The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power-supply solutions. MAX17670, MAX17671, and MAX17672 are dual-output regulators integrating a 4V to 60V, 150mA high-voltage, high-efficiency, Himalaya synchronous step-down converter with internal MOSFETs and a high-PSRR, low-noise, 2.35V to 5.5V, 50mA linear regulator. The MAX17670 and MAX17671 provide fixed step-down converter output voltages
of 3.3V and 5V, respectively. The output voltage of
the MAX17672 step-down converter is adjustable (0.8V
up to 90% of VIN). 3.3V (MAX17671 and MAX17672
only), 3.0V, 2.5V, 1.8V, 1.5V, and 1.2V linear regulator
output voltage options are supported.
The feedback-voltage regulation accuracy over -40°C
to +125°C temperature range for the linear regulator
is ±1.3% and for the step-down converter is ±2%. The
devices are available in a compact 10-pin (3mm x 3mm)
TDFN package. Simulation models are available.
