The upward slope of the switch current is due to the ramping up of the sx current. The EX series solves all of the difficulties associated with fiber sensors, such as: If the feedback voltage remains above 1.
This is thought to be very effective, giving excellent transient performance, but its stability is not well understood. The enclosed replaceable basic switch is accessible when the cover is removed.

This chip has been around for quite a while and is very inexpensive. The RC integrators in the flip flop are also needed for the same reason. A set-reset flip flop is held in the reset state during the discharge cycle, causing the output switching transistor to turn off. The charge current is modified by a voltage at the Ipk-sense pin to shorten the charge time and so reduce the maximum duty cycle. The oscillator-source block generates the timing capacitor current in response to the output of the comparator.

For designing dc-dc converters, the datasheets have a table of formulas that may be used, however this should not be a replacement for understanding of the circuit operation as the designs may need to be tweaked for a variety fx reasons.
The time constant of these must be much shorter than the width of the delay pulses. On a practical note, take extra care with board layout.
While it is no replacement for measurements on hardware, it can provide quite good behavioural modelling of complex circuits, allowing many errors and problems to be corrected before the hardware is built.
During the charging period the flip flop is set when the voltage at the feedback input pin 5 falls below 1. The blue plot is the voltage across the current limiting resistor R0, which is proportional mainly to the current through the output switch BJT.
The signal “oscillator” provides a pulse that goes low when the capacitor is being discharged. With its wide bandwidth and high linearity, the INA- is suitable as a driver amplifier for various applications.
Buck Converter This is a straightforward dc-dc converter that produces an output voltage less than the input xe. Here is a set of notes on the MC smps controller chip.
It is useful in applications such as providing analogue positive and negative supplies from a single 5V logic supply in small circuit boards.

The EX series achieves long distance sensing [thru-beam type: The circuit in the top left of the diagram above is the oscillator. It is also valuable for gaining an intuition into how circuits work. These chips can be sensitive to noise on the power input rails, resulting in the flip flop triggering prematurely and resulting in poor regulation and overvoltage.
