Description
Application Information
1
RTN
Ground
Ground connection of the integrated circuit.
2
VIN
Input Voltage
Operating input range is 7.5 V to 100 V.
3
UVLO
Input Pin of Undervoltage
Resistor divider from VIN to UVLO to GND programs the undervoltage detection
Comparator
threshold. An internal current source is enabled when UVLO is above 1.225V to
provide hysteresis. When UVLO pin is pulled below 0.66V externally, the parts
goes in shutdown mode.
4
RON
On-Time Control
A resistor between this pin and VIN sets the switch on-time as a function of VIN.
Minimum recommended on-time is 100ns at max input voltage.
5
FB
Feedback
This pin is connected to the inverting input of the internal regulation comparator.
The regulation level is 1.225V.
6
VCC
Output from the Internal High
The internal VCC regulator provides bias supply for the gate drivers and other
Voltage Series Pass Regulator.
internal circuitry. A 1.0
μF decoupling capacitor is recommended.
Regulated at 7.6V.
7
BST
Bootstrap Capacitor
An external capacitor is required between the BST and SW pins (0.01
μF
ceramic). The BST pin capacitor is charged by the VCC regulator through an
internal diode when the SW pin is low.
8
SW
Switching Node
Power switching node. Connect to the output inductor and bootstrap capacitor.
EP
Exposed Pad
Exposed pad must be connected to RTN pin. Connect to system ground plane on
application board for reduced thermal resistance.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
