MAX1846EUB Description

Short technical summary and product information.

The MAX1846EUB is a high-efficiency PWM inverting controller designed by Analog Devices / Maxim Integrated for compact, low-noise, negative-output DC-DC converters. It supports a wide input voltage range of +3V to +16.5V and can produce output voltages from -500mV to -200V.

 

This controller features a current-mode, constant-frequency PWM control scheme, allowing the operating frequency to be set between 100kHz and 500kHz via an external resistor. It is designed to drive a P-channel MOSFET, enabling converters to deliver up to 30W. The device is available in an ultra-compact 10-pin µMAX package, facilitating small form factor designs.

 

Key features include internal soft-start, compatibility with both electrolytic and ceramic output capacitors, and a maximum duty cycle of 96%. The MAX1846EUB is suitable for applications such as cellular base stations, networking equipment, optical networking, SLIC supplies, CO DSL line driver supplies, industrial power supplies, servers, and VOIP supplies.

 

It is offered in a surface mount package with a 10-uMAX supplier package designation. The operating temperature range is -40°C to +85°C (TA).
