Features
modulators are designed to be used in high-frequency,
switching power supplies in either voltage or current-mode
configurations. These designs 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.
The IS-1825ASRH, IS-1825BSRH, and IS-1825BSEH feature
dual, alternating output operating from zero to less than 50%
duty-cycle, while the ISL71823ASRH and ISL71823BSRH
features dual, in-phase output operating from zero to less than
100% duty cycle. The “B” versions test the delay from clock out
to PWM output switching after power has been applied to the
modulator (tPWM) (see Figure 3 on page 3). The IS-1825BSEH
is wafer-by-wafer acceptance tested to 50krad(Si) at a low
dose rate of 10mrad(Si)/s. Electrically screened to DLA SMD# 5962-02511 QML qualified per MIL-PRF-38535 requirements EH version is wafer-by-wafer acceptance tested to
