The MAX1847EEE+ is a high-efficiency, current-mode, PWM inverting controller from Analog Devices. It is designed to enable compact, low-noise, negative-output DC-DC converters for various telecom and networking applications. The device operates from a +3V to +16.5V input range and can generate output voltages from -500mV to -200V.
Key features include a current-mode, constant-frequency PWM control scheme that allows the operating frequency to be set from 100kHz to 500kHz via an external resistor. This controller offers 90% efficiency and drives a high-side P-channel MOSFET. The MAX1847 variant includes clock synchronization and shutdown functions, and can be configured as an inverting flyback controller for higher power outputs.
This controller is available in a 16-pin QSOP package, suitable for surface mount applications. Its design supports both electrolytic and ceramic output capacitors, offering flexibility in component selection. The current-mode control simplifies compensation and improves transient response, while low-side current sensing provides accurate control and over-current protection.
Applications include cellular base stations, networking equipment, optical networking, SLIC supplies, CO DSL line driver supplies, industrial power supplies, servers, and VOIP supplies.
