Applications Information
The ISL97519 is a high frequency, high efficiency boost
regulator operated at constant frequency PWM mode. The
boost converter stores energy from an input voltage source
and delivers it to a higher output voltage. The input voltage
range is 2.3V to 5.5V and the output voltage range is 5V to
25V. The switching frequency is selectable between 600kHz
and 1.2MHz allowing smaller inductors and faster transient
response. An external compensation pin gives the user greater
flexibility in setting output transient response and tighter load
regulation. The converter soft-start characteristic can also be
controlled by the external C SS capacitor. The EN pin allows the
user to completely shut-down the device.
as shown in Figure 11, the internal power FET turns on and the
Schottky diode is reverse biased and cuts off the current flow
to the output. The output current is supplied from the output
capacitor. The voltage across the inductor is V IN and the
inductor current ramps up in a rate of V IN /L, L is the
inductance. The inductance is magnetized and energy is stored
in the inductor. The change in inductor current is shown in
Equation 1:

Boost Converter Operations
Figure 10 shows a boost converter with all the key
components. In steady-state operating and continuous
conduction mode where the inductor current is continuous, the
boost converter operates in two cycles. During the first cycle,
