MAX777LESA Description

Short technical summary and product information.

The MAX777LESA is a pulse-skipping DC-DC converter manufactured by Analog Devices (formerly Maxim Integrated). It is designed for step-up voltage conversion from low-voltage inputs, guaranteeing start-up under load from as low as 1V. The device requires only three external components: an inductor and two capacitors.

Key features include an Active Rectifier technology that eliminates the need for an external catch diode and allows regulation even when the input voltage is higher than the output. This technology also disconnects the output from the source in shutdown mode, reducing current drain. The MAX777LESA operates at high frequencies up to 150kHz, enabling the use of small surface-mount inductors.

This converter offers high efficiency of up to 82% and low supply current, drawing only 190µA under no load and 20µA in standby mode. It is available in a SOP8 package and is suitable for applications such as single battery-cell operation, portable instruments, and notebook computers.

With a 2V input, the MAX777L typically delivers 200mA at 5V or 300mA at 3V. The MAX778L variant offers pin-selectable 3.0V or 3.3V outputs, while the MAX779L allows adjustable output from 2.5V to 6V via an external resistive divider.
