MAX1847EEE Description

Short technical summary and product information.

The MAX1847EEE is a high-efficiency, current-mode, inverting Pulse Width Modulation (PWM) controller from Analog Devices. It enables the design of compact, low-noise, negative-output DC-DC converters suitable for telecom and networking applications.

 

This controller operates with an input voltage range of +3V to +16.5V and can produce negative output voltages from -500mV to -200V. It features a constant-frequency PWM control scheme for minimized switching noise, with an operating frequency adjustable from 100kHz to 500kHz via an external resistor. The device boasts up to 90% efficiency.

 

The MAX1847EEE includes features such as clock synchronization and shutdown functions. It can be configured as an inverting flyback controller using an N-channel MOSFET and a transformer, capable of delivering up to 70W. Current-mode control simplifies compensation and enhances transient response, with over-current protection achieved through low-side current sensing.

 

Packaged in a 16-pin QSOP, the MAX1847EEE is designed for surface mount applications. Its design supports compatibility with both electrolytic and ceramic output capacitors, offering flexibility in component selection to minimize cost or optimize performance.
