Product Summary

The LAS6381P1 is a monolithic integrated circuit. The LAS6381P1 is designed for fixed frequency, pulse width modulated, switching converter applications such as step-down, step-up, flyback, forward, Cuk and voltage inverting DC-to-DC converters and motor controls. The LAS6381P1 series includes a temperature compensated voltage reference, sawtooth oscillantor with over-current frequency shift, linear trailing edge pulse width modulator with dounle pulse suppression logic, transconductance error amplifier, and an 8 amp Darlinton output transistor with internal current limit protection.
