Overview

DATASHEET IS-1825xSRH, IS-1825BSEH, ISL71823xSRH Single Event and Total Dose Hardened, High-Speed Dual Output PWMs FN9065 Rev.7.01 Jan 6, 2022 The IS-1825ASRH, IS-1825BSRH, IS-1825BSEH, ISL71823ASRH, and ISL71823BSRH are single event and total dose hardened pulse width modulators designed to be used in high-frequency switching power supplies in either voltage or current-mode configurations.

These devices include a precision voltage reference, a low power start-up circuit, a high-frequency oscillator, a wide-band error amplifier, and a fast current-limit comparator.

Key Features

  • dual in-phase output operating from zero to less than 100% duty cycle. The B versions of the parts test the delay from clock out to PWM output switching after power has been applied to the modulator (tPWM) (see Figure 2 on page 9). The SEH parts are wafer-by-wafer acceptance tested to 50krad(Si) at a low dose rate of.
