Pin connections and functions
L6730C - L6730D
8/50
4
TMASK
By connecting this pin to VCCDR or ground it is possible to select two different
values for the leading edge blanking time on the peak-over-current-protection.
The device captures the analog value present at this pin at the start-up when
VCC meets the UVLO threshold.
5
GND
All the internal references are referred to this pin.
6FB
This pin is connected to the error amplifier inverting input. Connect it to Vout
through the compensation network. This pin is also used to sense the output
voltage in order to manage the over voltage conditions and the PGood signal.
7COMP
This pin is connected to the error amplifier output and is used to compensate
the voltage control loop.
8
SS/INH
The soft-start time is programmed connecting an external capacitor from this
pin and GND. The internal current generator forces a current of 10
µA through
the capacitor. This pin is also used to inhibit the device: when the voltage at
this pin is lower than 0.5V the device is disabled.
9
EAREF
It is possible to set two internal references 0.6V / 1.2V or provide an external
reference from 0V to 2.5V:
VEAREF from 0% to 80% of VCCDR −> External Reference
VEAREF from 80% to 95% of VCCDR −> VREF=1.2V
VEAREF from 95% to 100% of VCCDR −> VREF=0.6V
An internal clamp limits the maximum VEAREF at 2.5V (typ.). The device
captures the analog value present at this pin at the start-up when VCC meets
the UVLO threshold.
10
OSC
Connecting an external resistor from this pin to GND, the external frequency
can be increased according with the following equation:
Connecting a resistor from this pin to VCCDR (5V), the switching frequency can
be lowered according with the following equation:
If the pin is left open, the switching frequency is 400 KHz. Normally this pin is at
a voltage of 1.2V. In OVP the pin is pulled up to 4.5V (only in latched mode).
Don’t connect a capacitor from this pin to GND.
