Function Block Diagram
Operation
Internal Regulator
Provide internal power for logic control and switch gate
drivers.
Shutdown Comparator
Activate internal regulator once EN input level is higher
than the target level. Force IC to enter shutdown mode
when the EN input level is lower than 0.4V.
Lockout Comparator
Activate the current comparator, release lock-out logic,
and enable the switches as EN input level is higher than
lockout threshold voltage. Otherwise, the switches still
lock out.
Oscillator
The oscillator provides internal clock and controls the
converter's switching frequency.
Foldback Control
Dynamically adjust the internal clock. It provides a slower
frequency as a lower FB voltage.
UV Comparator
As FB voltage is lower than the UV voltage, it will activate
a UV protect scheme.
Error Amplifier
The output voltage COMP of the error amplifier is adjusted
by comparing FB signal with the internal reference voltage
and SS signal.
Current Sense Amplifier
RSENSE detects the peak current of the high side switch.
This signal is amplified by the current sense amplifier and
added with a slope compensation signal. Then, It controls
the switches by comparing this signal with the COMP
voltage.
