Operation Description
LM4510 is a peak current-mode, fixed-frequency PWM boost
regulator
that
employs
both
Synchronous
and
Non-Synchronous Switching.
The DC/DC regulator regulates the feedback output voltage
providing excellent line and load transient response. The op-
eration of the LM4510 can best be understood by referring to
the Block Diagram.
NON-SYNCHRONOUS OPERATION
The device operates in Non-synchronous Mode at light load
(I
OUT < 10 mA) or when output voltage is lower than 10V (typ.).
At light load, LM4510 automatically changes its switching op-
eration from 'Synchronous' to 'Non-Synchronous' depending
on V
IN and L. Non-Synchronous operation at light load maxi-
mizes power efficiency by reducing PMOS driving loss.
OPERATION IN SYNCHRONOUS CONTINUOUS
CONDUCTION MODE (CYCLE 1, CYCLE 2)
