The MAX1705EEE by Analog Devices / Maxim Integrated is a high-efficiency, low-noise step-up DC-DC converter designed for battery-powered wireless applications. It utilizes a synchronous rectifier pulse-width-modulation (PWM) boost topology to generate adjustable outputs from 2.5V to 5.5V from battery inputs.
Key electrical specifications include an input voltage range starting at 0.9V, an output current capability of 1A (switch), and a switching frequency between 260kHz and 340kHz. The device boasts up to 96% efficiency and a guaranteed startup at 1.1V. It also includes a built-in low-dropout linear regulator capable of delivering up to 200mA with an adjustable output from 1.25V to 5.0V.
This converter operates within a temperature range of -40°C to 85°C (TA) and is housed in a 16-QSOP package, suitable for surface mounting. The MAX1705EEE offers features like a 1µA shutdown mode and pushbutton on/off control, making it versatile for various portable electronic designs.
Applications include digital cordless phones, PCS phones, personal communicators, wireless handsets, palmtop computers, two-way pagers, and handheld instruments.
