PIN DESCRIPTIONS (continued)
Pin(s)
Name
Description
Application Information
8
RAMP
Ramp control signal
An external capacitor connected between this pin and the AGND
pin sets the ramp slope used for current mode control.
Recommended capacitor range 50pF to 2000pF.
9
AGND
Analog ground
Internal reference for the regulator control functions
10
SS
Soft-start
An external capacitor and an internal 10µA current source set
the time constant for the rise of the error amp reference. The SS
pin is held low during standby, Vcc UVLO and thermal
shutdown.
11
OUT
Output voltage connection
Connect directly to the regulated output voltage.
12
PGND
Power ground
Low side reference for the PRE switch and the IS sense resistor.
13
IS
Current sense
Current measurement connection for the re-circulating diode. An
internal sense resistor and a sample/hold circuit sense the diode
current near the conclusion of the off-time. This current
measurement provides the DC level of the emulated current
ramp.
14
SW
Switching node
The source terminal of the internal buck switch. The SW pin
should be connected to the external Schottky diode and to the
buck inductor.
15
PRE
Pre-charge assist for the bootstrap
This open drain output can be connected to SW pin to aid
capacitor
charging the bootstrap capacitor during very light load conditions
or in applications where the output may be pre-charged before
the LM25575 is enabled. An internal pre-charge MOSFET is
turned on for 250ns each cycle just prior to the on-time interval
of the buck switch.
16
BST
Boost input for bootstrap capacitor
An external capacitor is required between the BST and the SW
pins. A 0.022µF ceramic capacitor is recommended. The
capacitor is charged from Vcc via an internal diode during the
off-time of the buck switch.
NA
EP
Exposed Pad
Exposed metal pad on the underside of the device. It is
recommended to connect this pad to the PWB ground plane, in
order to aid in heat dissipation.
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.

(1)
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which
operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics.
(2)
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3)
The human body model is a 100pF capacitor discharged through a 1.5k
Ω resistor into each pin.
