Si4442DY Datasheet N-channel Fet

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM2727/LM2737 N-Channel FET Synchronous Buck Regulator Controller for Low Output Voltages June 2003 LM2727/LM2737 N-Channel FET Synchronous Buck Regulator Controller for Low Output.

General Description

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.

Key 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 limit is achieved by monitoring the voltage drop across the onresistance of the low-side MOSFET, which enhances low duty-cycle operation. The wide range of operating frequencies gives the power supply d.
