The LT3999EMSE#PBF by Analog Devices is a monolithic, high voltage, high frequency DC/DC transformer driver designed for isolated power solutions in a small footprint. It incorporates dual 1A current-limited power switches that operate out of phase, allowing for adjustable output voltage through duty cycle control. The switching frequency can be programmed from 50kHz up to 1MHz and synchronized to an external clock.
Key electrical specifications include a wide input operating range from 2.7V to 36V and a programmable switching frequency up to 1MHz. The device features programmable input over and undervoltage lockouts and a low shutdown current of less than 1µA. It also includes cross-conduction prevention circuitry and a programmable soft-start capability to limit inrush current.
This DC/DC driver is available in a 10-lead MSOP package with an exposed pad. The surface mountable design is suitable for various applications requiring low noise isolated supplies, distributed power, positive-to-negative supplies, and noise immunity in data acquisition systems.
Applications include medical instruments, safety equipment, distributed power systems, multiple output supplies, positive-to-negative supplies, and noise immunity for RS232 and RS485 communication.
