Elektronische Bauelemente

150KHz 3A Step-Down Voltage Regulator

Description

The S5ELM2596 series of regulators are monolithic integrated

circuits that provide all active functions for a step-down (buck)

switching regulator, capable of driving 3A load with excellent line

and load regulation. These devices are available in fixed output

voltage of 3.3V,5V,12V and an adjustable output version.Requiring

a min. rumber of external components, these regulators are simple

to use and include internal frequency components and a fixed-

frequency oscillator. The S5ELM2596 series operates at a switching

frequency of 150KHz thus allowing smaller sized filter components

than what would be needed with lower frequency switching requlators.

Available in a standard 5-lead TO-220 package with several different

lead bend options. A standard series if inductors are available from

several differnet manufactures optimized for use with the S5ELM2596

series.

The feature greatly simplifies the design

of switching-mode

power supplies. Other feature include a guaranteed 4% to tolerance

on output voltage within specified input voltages and output load

condition, and 15% on the oscillator frequency. External shutdown

is included, featuring 80uA(Typ.) standby current. The output switch

includes cycle-by-cycle current limiting, as well as thermal shutdown

for full protection under fault condition.
