Datasheet Details
The LM2727 and LM2737 are high-speed, synchronous, switching regulator controllers.
They are intended to control currents of 0.7A to 20A with up to 95% conversion efficiencies.
The LM2727 employs output over-voltage and undervoltage latch-off.
For applications where latch-off is not desired, the LM2
A220 Features
* The LM2737 and LM2737 operate from a low-current 5V bias and can convert from a 2.2V to 16V power rail. Both parts utilize a fixedfrequency, voltage-mode, PWM control architecture and the switching frequency is adjustable from 50kHz to 2MHz by adjusting the value of an external resistor. Current li
