Block Diagram
Pin Description
Pin No. Symbol Description
1 PGND Ground pin for the output section
2 V
IN1
Input pin for the output section
This pin is placed in the standby state if V
EN
= low. Standby current is 10 μA or less.
3 V
IN2
Input pin for the control section
This pin is placed in the standby state if V
EN
= low. Standby current is 10 μA or less.
4 SGND Ground pin for the control section
5 V
FB
Feedback pin
This input is fed into an internal error amplifier with a reference voltage of 0.8 V (typ.).
6 SS
Soft-start pin
When the SS input is left open, the soft-start time is 1 ms (typ.). The soft-start time can be adjusted
with an external capacitor. The external capacitor is charged from a 8-μA (typ.) constant-current
source, and the reference voltage of the error amplifier is regulated between 0 V and 0.8 V. The
external capacitor is discharged when EN = low and in case of undervoltage lockout or thermal
shutdown.
7 EN
Enable pin
When EN ≥ 1.5 V (@ V
IN
= 5 V), the internal circuitry is allowed to operate and thus enable the
switching operation of the output section. When EN ≤ 0.5 V (@ V
IN
= 5 V), the internal circuitry is
disabled, putting the TCV7100AF in Standby mode.
This pin has an internal pull-down resistor of approx. 500 kΩ.
