EVALUATION KIT AVAILABLE

MAX17290/MAX17292

2.5V to 36V, 2.5MHz, PWM Boost Controller

with 4µA Shutdown Current and Reduced EMI

General Description

Beneﬁts and Features

● Reduces Solution Size and Cost

• All-Ceramic Capacitor Solution Allows Ultra-Compact

Solution Size

The MAX17290/MAX17292 high-efficiency, synchronous

step-up DC-DC controllers operate over a 4.5V to 36V

input voltage range with 42V input transient protection.

The input operating range can be extended to as low as

2.5V in Bootstrapped mode.

• 100kHz to 1MHz (MAX17290) and 1MHz to

2.5MHz (MAX17292) Switching-Frequency with

External Synchronization

The MAX17290 and MAX17292 use a constant-frequency,

pulse-width modulating (PWM), peak current-mode

control architecture. There are multiple versions of the

devices offering one or more of the following functions:

a synchronization output (SYNCO) for 180° out-of-phase

operation, an overvoltage protection function using a

separate input pin (OVP), and a reference input pin

(REFIN) to allow on-the-fly output voltage adjustment.

● Increases Design Flexibility

• Bootstrapped Mode Allows Input Voltage to be 2.5V

• Adjustable Slope Compensation

● Reduces Power Dissipation

• >90% Peak Efﬁciency

• Low 4μA (typ.) Shutdown Current

● Operates Reliably

The MAX17290 and MAX17292 operate in different

frequency ranges. All versions can be synchronized to an

external master clock using the FSET/SYNC input.

• 42V Input Voltage Transient Protection

• Fixed 9ms Internal Software Start Reduces Input

Inrush Current

• PGOOD Output and Hiccup Mode for Enhanced

System Protection

• Overtemperature Shutdown

• Reduced EMI Emission with Spread-Spectrum

Control

The devices are available in a compact 12-pin (3mm x

3mm) TQFN and 10-pin µMAX packages. Both packages

have exposed pads. -40°C to +85°C Operation.
