DESCRIPTION

KEY FEATURES

■ IMPROVED REFERENCE INITIAL

TOLERANCE (±1% max.)

The SG1825C is a high-performance

pulse width modulator optimized for

high frequency current-mode power

supplies. Included in the controller

are a precision voltage reference,

micropower start-up circuitry, soft-

start, high-frequency oscillator,

wideband error amplifier, fast current-

limit comparator, full double-pulse

suppression logic, and dual totem-

pole output drivers. Innovative

circuit design and an advanced linear

Schottky process result in very short

propagation delays through the

current limit comparator, logic, and

output drivers. This device can be

used to implement either current-

mode or voltage-mode switching

power supplies. It also is useful as

a series-resonant controller to

frequencies beyond 1MHz. The

SG1825C is specified for operation

over the full military ambient tem-

perature range of -55°C to 125°C.

The SG2825C is characterized for the

industrial range of -25°C to 85°C,

and the SG3825C is selected for the

commercial range of 0°C to 70°C.
