1- to 3-Cell, High-Current, Low-Noise,
Step-Up DC-DC Converters with Linear Regulator
General Description
The MAX1705/MAX1706 are high-efficiency, low-noise,
step-up DC-DC converters with an auxiliary linear-
regulator output. These devices are intended for use in
battery-powered wireless applications. They use a syn-
chronous rectifier pulse-width-modulation (PWM) boost
topology to generate 2.5V to 5.5V outputs from battery
inputs, such as 1 to 3 NiCd/NiMH cells or 1 Li-Ion cell.
The MAX1705 has an internal 1A n-channel MOSFET
switch. The MAX1706 has a 0.5A switch. Both devices
also have a built-in low-dropout linear regulator that
delivers up to 200mA.
With an internal synchronous rectifier, the MAX1705/
MAX1706 deliver 5% better efficiency than similar non-
synchronous converters. They also feature a pulse-
frequency-modulation (PFM) standby mode to improve
efficiency at light loads, and a 1μA shutdown mode. An
efficiency-enhancing track mode reduces the step-up
Features
? Up to 96% Efficiency
? 1.1V IN Guaranteed Startup
? Up to 850mA Output (MAX1705)
? Step-Up Output (2.5V to 5.5V Adjustable)
? Linear Regulator (1.25V to 5.0V Adjustable)
? PWM/PFM Synchronous-Rectified Topology
? 300kHz PWM Mode or Synchronizable
? 1μA Shutdown Mode
? Voltage Monitor
? Pushbutton On/Off Control
Ordering Information
DC-DC converter output to 300mV above the linear-reg-
ulator output.
Both devices come in a 16-pin QSOP package, which
occupies the same space as an 8-pin SO. Other features
