MSP1250
Power Converter 150kHz 3A
Step-down Voltage Regulator
Note 3:
Typical numbers are at 25
Note 4:
All limits guaranteed at room temperature (standard type face) and at temperature
extremes (bold type face). All room temperature limits are 100% production tested. All
limits at temperature extremes are guaranteed via correlation using standard Statistical
Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality
Level (AOQL).
Note5:
External components such as the catch diode, inductor, input and output capacitors,
and voltage programming resistors can affect switching regulator system performance.
Note 6:
The switching frequency is reduced when the second stage current limit is
activated.
Note 7:
No diode, inductor or capacitor connected to output pin.
Note 8:
Feedback pin removed from output and connected to 0V to force the output
transistor switch ON.
Note 9:
Feedback pin removed from output and connected to 12V for the 3.3V, 5V, and the
ADJ. version, and 15V for the 12V version, to force the output transistor switch OFF.
Note 10:
V
IN
= 40V.
Note 11:
Junction to ambient thermal resistance (no external heat sink) for the TO-220
package mounted vertically, with the leads soldered to a printed circuit board with
(1 oz.) copper area of approximately 1 in
2
.
Note 12:
Junction to ambient thermal resistance with the TO-263 package tab soldered to a
single printed circuit board with 0.5 in
2
of (1 oz.) copper area.
Note 13:
Junction to ambient thermal resistance with the TO-263 package tab soldered to a
single sided printed circuit board with 2.5 in
2
of (1 oz.) copper area.
Note 14:
Junction to ambient thermal resistance with the TO-263 package tab soldered to a
double sided printed circuit board with 3 in
2
of (1 oz.) copper area on the MSP1250 side of
the board, and approximately 16 in
2
of copper on the other side of the p-c board.
and represent the most likely norm.
