Function
15
SGND
All the internal references are referred to this pin.
16
FB
This pin is connected to the error amplifier inverting input. Connect it to V
OUT
through
the compensation network. This pin is also used to sense the output voltage in order
to manage the over voltage protection.
1
COMP
This pin is connected to the error amplifier output and is used to compensate the
voltage control feedback loop.
2
SS/INH
The soft-start time is programmed connecting an external capacitor from this pin to
GND. The internal current generator forces a current of 10
μ
A through the capacitor.
When the voltage at this pin is lower than 0.5V the device is disabled.
3
EAREF
By setting the voltage at this pin is possible to select the internal/external reference
and the switching frequency:
V
EAREF
0-80% of V
CCDR
-> External Reference/F
SW
= 250KHz
V
EAREF
= 80% - 95% of V
CCDR
-> V
REF
= 0.6V/F
SW
= 500KHz
V
EAREF
= 95% - 100% of V
CCDR
->V
REF
= 0.6V/F
SW
= 250KHz
An internal clamp limits the maximum V
EAREF
at 2.5V (typ.). The device captures the
analog value present at this pin at the start-up when V
CC
meets the UVLO threshold.
