概要
説明
The radiation hardened HS-1825ARH, HS-1825AEH pulse width modulator is designed to be used in high-frequency switched-mode power supplies and can be used in either current-mode or voltage-mode. It is well suited for single-ended boost converter applications. Device features include a precision voltage reference, low power start-up circuit, high-frequency oscillator, wide-band error amplifier and fast current-limit comparator. The use of proprietary process capabilities and unique design techniques results in fast propagation delay times and high output current over a wide range of output voltages. Constructed with the Intersil radiation hardened Silicon Gate (RSG) Dielectric Isolation BiCMOS process, the HS-1825ARH, HS-1825AEH have been specifically designed to provide highly reliable performance when exposed to harsh radiation environments..
