Description

General part information

MAX77720 Series

The MAX77720 dual-output DC-DC converter generates two independently regulating positive and negative supply voltages. The positive output delivers up to 4W of power at the output while the negative output delivers up to 4.8W of power. The MAX77720 is ideal for powering time of flight (ToF) imaging sensors and OLED displays in smart internet of things (IoT) devices.The MAX77720 generates an adjustable negative output down to -24V and a positive output voltage up to +20V. The negative output operates at a fixed 1.5MHz frequency while the positive output operates at a fixed 1MHz frequency to ease noise filtering in sensitive applications and to reduce external component size.The nERR pin, when connected to an external device’s output pin, is used to disable the regulators to signal an external error. This error can be cleared through I2C from a host processor to re-enable the regulators. While in the error on state, there is an option for the active discharge to be enabled or disabled (for example, to set the regulator outputs to a high-Z floating).A bidirectional I2C serial interface allows for configuring and checking the status of the devices. Numerous factory-programmable options allow the device to be tailored for many applications, enabling faster time to market.APPLICATIONSToF SensorsOLED DisplaysBipolar Amplifiers
