Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
If I
FB
is taken below GND, it is clamped by an internal diode. This
pin handles input currents
≤
100mA below GND without latch-up. In the
positive direction, it is not clamped to PV
CC
.
Note 3:
All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 4:
The LTC1530 is tested in an op amp feedback loop which
regulates V
SENSE
or V
OUT
based on V
COMP
= 2V for the error amplifier.
Note 5:
The Open-loop DC gain and transconductance from the V
FB
pin to
the COMP pin are G
ERR
and g
mERR
respectively. For fixed output voltage
versions, the actual open-loop DC gain and transconductance are G
ERR
and g
mERR
multiplied by the ratio 1.235/V
OUT
.
Note 6:
The total voltage from the PV
CC
pin to the GND pin must be
≥
8V
for the current limit protection circuit to be active.
Note 7:
G1 and G2 begin to switch once PV
CC
is
≥
the undervoltage
lockout threshold voltage.
Note 8:
Supply current in normal operation is dominated by the current
needed to charge and discharge the external FET gates. This current varies
with the LTC1530 operating frequency, supply voltage and the external
FETs used.
Note 9:
The LTC1530 enters shutdown if COMP is pulled low.
Note 10:
Slew rate is measured at the COMP pin on the transition from
shutdown to active mode.
The
G

range, otherwise specifications are at –40
