ActiveCURRENT MODE PWMS ISOLATED SWITCHING REGULATORS - CURRENT MODE PWM, 1.5MHZ
Description
General part information
SG1825C Series
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, micro power 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 temperature range of -55°C to 125°C.
