Its 97% maximum duty cycle means the output can ride within a few percent of the input rail — essential for a boost converter that must hold regulation as the input sags, or for a forward converter that needs to maximise volt-seconds on the transformer primary. The part is in a 16-pin PDIP through-hole package, suited for prototyping, low-volume production, and designs where rework ease matters more than board density.
Switching frequency and supply — sizing the passives
The switching frequency spans 1 kHz to 300 kHz. The supply range of 7 V to 40 V covers standard industrial buses.
Control features and temperature grade
Dead-time control and frequency control are on-chip, letting you set the overlap between the two output phases and synchronise the oscillator to an external clock if needed — though the part does not include a dedicated clock-sync pin, so synchronisation is done by injecting a signal into the RT/CT pin. No synchronous rectifier driver is included, so the output stage uses Schottky or ultrafast diodes on the secondary side.
The 16-PDIP package ships in tube form, which is typical for through-hole ICs in production runs and prototyping alike.
