Product Overview

The MAX1706EEE+ is a 1-cell to 3-cell, high current, low noise, step-up DC-DC converter with linear regulator in 16 pin QSOP package. It use a synchronous 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. It has a built-in low-dropout linear regulator that delivers up to 200mA. With an internal synchronous rectifier, MAX1706 deliver 5% better efficiency than similar nonsynchronous converters. It also features 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 DC-DC converter output to 300mV above the linear regulator output. It is used in digital cordless phones, personal communicators, palmtop computers, wireless handsets, PCS phones and two-way pagers.
  • Minimum operating battery voltage is 0.7V (typ), 1.1VIN start-up voltage
  • Operating temperature range from -40°C to 85°C
  • FB regulation voltage is 1.233V at CLK/SEL = OUT
  • Up to 96% efficiency
  • Step-up output (2.5V to 5.5V adjustable)
  • Linear regulator (1.25V to 5V adjustable)
  • PWM/PFM synchronous rectified topology
  • 300KHz PWM mode or synchronized
  • 1µA shutdown mode
  • Voltage monitor, pushbutton on/off control
