HS-1825ARH中文资料Radiation Hardened High-speed, Dual Output PWM数据手册Renesas规格书

描述 Description

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.
