MAX17670, MAX17671,

MAX17672

Integrated 4V-60V, 150mA, High-Eﬃciency,

Synchronous Step-Down DC-DC Converter

with 50mA Linear Regulator

General Description

Beneﬁts and Features

The Himalaya series of voltage regulator ICs, power

modules, and chargers enable cooler, smaller, and sim-

pler 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-

● Reduces External Components and Total Cost

• No Schottky–Synchronous Operation

• Internal Compensation

• Built-In Soft-Start

• All-Ceramic Capacitors, Compact Layout

•

Protection against Inductive Short at Step-Down

Converter Output

● Reduces Number of DC-DC Regulators to Stock

• Wide 4V to 60V Input Range for the Step-Down

Converter Regulator

• Up to 98% Duty-Cycle Step-Down Operation

• 200kHz to 2.2MHz Adjustable Switching Frequency

with External Synchronization for Step-down

Converter

• 2.35V to 5.5V, Input Range for the Linear Regulator

• Linear Regulator with up to 50mA Load Current

Capability

down converter is adjustable (0.8V up to 90% of V ).

3.3V (MAX17671 and MAX17672 only), 3.0V, 2.5V, 1.8V,

1.5V, and 1.2V linear regulator output voltage options are

supported. See the Ordering Information for details.

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.
