SG1524/SG2524/SG3524
Regulating Pulse Width Modulator
Description
This monolithic integrated circuit contains all the control
circuitry for a regulating power supply inverter or switching
regulator. Included in a 16-pin dual-in-line package is the
voltage reference, error amplifier, oscillator, pulse width
modulator, pulse steering flip-flop, dual alternating output
switches and current limiting and shut-down circuitry. This
device can be used for switching regulators of either
polarity, transformer coupled DC to DC converters,
transformerless voltage doublers and polarity converters, as
well as other power applications. The SG1524 is specified
for operation over the full military ambient temperature
range of -55°C to +125°C, the SG2524 for -25°C to +85°C,
and the SG3524 is designed for commercial applications of
0°C to +70°C.
Features
8V to 40V Operation
5V Reference
Reference Line and Load Regulation of 0.4%
100Hz to 300kHz Oscillator Range
Excellent External Sync Capability
Dual 50mA Output Transistors
Current Limit Circuitry
Complete PWM Power Control Circuitry
Single Ended or Push-Pull Outputs

Now let's discuss the isolation specification of the switch when the signal is switched to a high impedance device.
Both the via isolation and the signal-to-chassis isolation must be higher than the resistance of the device under test to avoid measuring the switch card characteristics instead of the desired device ...
