Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LTC3783E is guaranteed to meet performance specifications
over the 0°C to 85°C operating temperature range. Specifications over
the –40°C to 85°C operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3783I is guaranteed to meet performance specifications over the full
–40°C to 125°C operating temperature range.
Note 3:
T
J
is calculated from the ambient temperature T
A
and power
dissipation P
D
according to the following formula:
T
J
= T
A
+ (P
D
• 43°C/W) for the DFN
T
J
= T
A
+ (P
D
• 38°C/W) for the TSSOP
Note 4:
The dynamic input supply current is higher due to power MOSFET
gate charging (Q
G
• f
OSC
). See Operation section.
Note 5:
The LTC3783 is tested in a feedback loop which servos V
FBN
to
V
FBP
= V
VREF
with the I
TH
pin forced to the midpoint of its voltage range
(0.3V ≤ V
ITH
≤ 1.2V; midpoint = 0.75V).
Note 6:
In a synchronized application, the internal slope compensation is
increased by 25%. Synchronizing to a significantly higher ratio will reduce
the effective amount of slope compensation, which could result in sub-
harmonic oscillation for duty cycles greater than 50%
Note 7:
Rise and fall times are measured at 10% and 90% levels.
Supply voltage (maximum): 36V Frequency: 20kHz ~ 1MHz Type: DC DC controller internal switch: None Topology: flyback, SEPIC, buck, boost Supply voltage (minimum): 3V PWM LED driver and boost, flyback Excitation and SEPIC type controllers
