PIN DESCRIPTION
AMS4154
PIN
NUMBERS
NAME
DESCRIPTION
1
BST
Bootstrap. A capacitor is needed to drive the power switch’s drive above the supply
voltage. It is connected between LX and BST pins to form a floating supply across the
power switch driver.
2
VIN
Supply Voltage. The AMS4154 operates from a+5.5V to +32V unregulated input. C1 is
needed to prevent large voltage spikes from appearing at the input.
3
LX
Switch. This connects the inductor to VIN through the internal power switch.
4
GND
Ground. This pin is the ground for voltage reference and for the regulated output voltage.
For this reason care must be taken in its layout.
5
FB
Feedback. An external resistor divider from the output to GND, tapped to the FB pin sets
the output voltage.
6
COMP
Compensation. This node is the output of the transconductance error amplifier and the
input to the current comparator. Frequency compensation is done at this node by
connecting a series R-C to ground.
7
EN
Enable. A voltage greater than 2.5V enables operation. For complete low current shutdown
the EN pin voltage needs to be less than 2.3V.
8
REF
5V reference voltage capable of supplying 1mA for other external circuits.
