4A, Low-Noise, High-Frequency,

Step-Up DC-DC Converter

MAX1709

General Description

Features

The MAX1709 sets a new standard of space savings for

high-power, step-up DC-DC conversion. It delivers up

to 20W at a fixed (3.3V or 5V) or adjustable (2.5V to

5.5V) output, using an on-chip power MOSFET from a

+0.7V to +5V supply.

♦ On-Chip 10A Power MOSFET

♦ 5V, 4A Output from a 3.3V Input

♦ Fixed 3.3V or 5V Output Voltage or

Adjustable (2.5V to 5.5V)

Fixed-frequency PWM operation ensures that the

switching noise spectrum is constrained to the 600kHz

fundamental and its harmonics, allowing easy postfilter-

ing for noise reduction. External clock synchronization

capability allows for even tighter noise spectrum con-

trol. Quiescent power consumption is less than 1mW to

extend operating time in battery-powered systems.

♦ Input Voltage Range Down to 0.7V

♦ Low Power Consumption

1mW Quiescent Power

1µA Current in Shutdown Mode

♦ Low-Noise, Constant Frequency Operation

(600kHz)

Two control inputs (ONA, ONB) allow simple push-on,

push-off control through a single momentary pushbut-

ton switch, as well as conventional on/off logic control.

The MAX1709 also features programmable soft-start

and current limit for design flexibility and optimum per-

formance with batteries.

♦ Synchronizable Switching Frequency

(350kHz to 1000kHz)

Ordering Informations

The MAX1709 is supplied in both a high-power TSSOP

package, which allows a 10A

switch current and a

RMS

4A output, and a narrow SO package, which supplies a

2.4A output with a switch rated at 6A . Although the

MAX1709ESE

MAX1709EUI+

RMS

narrow SO device has a lower RMS switch rating, it has

the same peak switch current rating as the TSSOP

device, and so can supply 4A loads intermittently. If

loads of 2A or less are required, refer to the MAX1708.

+Indicates lead(Pb)-free/RoHS-compliant package.
