MAX1846 Datasheet (Maxim) - High-Efficiency / Current-Mode / Inverting PWM Controller

MAX1846, High-Efficiency / Current-Mode / Inverting PWM Controller

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 device

MAX1846 Features

* clock synchronization and shutdown functions. The MAX1847 can also be configured to operate as an inverting flyback controller with an Nchannel MOSFET and a transformer to deliver up to 70W. The MAX1847 is available in a 16-pin QSOP package. Current-mode control simplifies compensation and provides
