MAX766EPA+

Voltage Regulators - DC DC Switching Regulators Overview

The MAX766EPA+ is a negative-output buck-boost switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 3V to 16V and provides an adjustable or fixed negative output ranging from -1V to -15V, with a maximum output current of 105mA. The device utilizes a buck-boost topology and features a switching frequency of 300kHz. It is housed in an 8-PDIP package and supports an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Provides negative voltage regulation using a buck-boost topology suitable for single-supply applications requiring inverted rails.

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative supply rails for operational amplifiers and analog circuits from positive sources.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the package type carefully, as the requested model suffix 'EPA+' indicates an 8-pin PDIP through-hole package. This differs significantly from the 'ESA+' variant, which uses an 8-SOIC surface-mount package. Ensure the PCB footprint matches the specific physical dimensions of the DIP-8 housing before procurement to avoid assembly errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a negative output voltage is required from a positive input source within the specified voltage limits. Consider the 105mA output current capability and the 300kHz switching frequency against system noise and efficiency requirements. Verify that the through-hole packaging aligns with the manufacturing process and board design constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX76x series of switching regulators designed for efficient power conversion. It integrates the necessary control logic and power switches to regulate negative voltages without requiring external inductors or complex feedback networks beyond standard resistor dividers. The series is intended for portable and battery-powered systems where space and efficiency are critical.
