LAS-3840

The LAS-3840 is a high performance monolithic integrated circuit switching regulator designed for use in fixed frequency power control applications such as switching power control applications such as switching power control applications such as switching power supplies and motor controls.Included in the dual in line hermetic and plastic packages are a temperature compensated voltage reference,under voltage lockout,sawtooth oscillator with over current frequency shift ,linear'trailing adge'pulse widdth modulator with double pulse suppression logic,error amplifier,high speed current limit comparator,two push-pull output devices with over-current protection,shutdown logic and provision for dynamic volt-time symmetry correction in double ended systems.

Features of the LAS-3840 are:(1)dynamic volt/time balancing; (2)cycle-by-cycle current limit; (3)current limit frequency limit; (4)programmable dead time; (5)temperature compenstated current limit.

The absolute maximum ratings of the LAS-3840 can be summarized as:(1)input voltage:40 v; (2)collector supply voltage:40v; (3)source/sink current:200mA; (4)thermal resistance junction to ambient:125 /watt.
