Description

OBSOLETE:  For Information Purposes Only.  Contact Linear Technology for Potential Replacement.

The LT1524 PWM switching regulator control circuit contains all the essential circuitry to implement single-ended or push-pull switching regulators. Included on the circuit are oscillator, voltage reference, a pulse width modulator, error amplifier, overload protection circuitry and output drivers. Although pin-for-pin and functionally compatible with industry standard 1524 and 3524 devices, Linear Technology has incorporated several improvements in the design of the LT1524. A subsurface zener reference has been used to provide excellent stability with time and the reference is trimmed at the wafer level to provide an initial accuracy of 2%. Additionally, the oscillator is trimmed to provide a maximum tolerance of 6%. Linear Technology Corporation's advanced processing, design and passivation techniques make the LT1524 and LT3524 a superior and more reliable choice over previous devices.
