3.3V/5V or Adjustable,

Step-Up/Down DC-DC Converters

_______________General Description

____________________________Features

♦ Step-Up/Down Voltage Conversion

♦ +1.8V to +11V Input Range

The MAX710/MAX711 integrate a step-up DC-DC con-

verter with a linear regulator to provide step-up/down

voltage conversion. They are optimized for battery

applications where the input varies above and below

the regulated output voltage. They have an input range

from +1.8V to +11V. Typical efficiency when boosting

battery inputs is 85%.

♦ Output:

5V/250mA at V = 1.8V

5V/500mA at V = 3.6V

♦ No External FETs Required

♦ Load Disconnected from Input in Shutdown

♦ Battery Drain:

The MAX710/MAX711 can be configured for minimum

noise or optimum efficiency. Shutdown control turns off

the part completely, disconnecting the input from the

output (I

= 0.2µA). Standby control turns off only

the step-up converter and leaves the low-power linear

regulator active (I = 7µA).

The MAX710 has a preset 3.3V or 5V output voltage.

The MAX711 has an adjustable output that can be set

from +2.7V to +5.5V with two resistors. Both devices

come in 16-pin narrow SO packages.

♦ Low-Noise and High-Efficiency Modes
