Overview
19-2091; Rev 0; 8/01
High-Efficiency, Current-Mode, Inverting PWM Controller
General Description
MAX1846/MAX1847 high-efficiency PWM inverting controllers allow designers to implement compact, lownoise, negative-output DC-DC converters for telecom and networking applications.
Both devices operate from +3V to +16.
5V input and generate -2V to -200V output.
To minimize switching noise, both devices feature a current-mode, constant-frequency PWM control scheme.
The operating frequency can be set from 100kHz to 500kHz through a resistor.
The MAX1846 is available in an ultra-compact 10-pin µMAX package.
Operation at high frequency, compatibility with ceramic capacitors, and inverting topology wit...
