Overview
Freescale Semiconductor Technical Data Document Number: MC33998 Rev.
2.
0, 8/2006 Switching Power Supply with Linear Regulators The 33998 is a medium-power, multi-output power supply integrated circuit that is capable of operating over a wide input voltage range, from 6.
0 V up to 26.
5 V with 40 V transient capability.
It incorporates a sensorless current mode control step-down switching controller regulating directly to 5.
0 V.
The 2.
6 V linear regulator uses an external pass transistor to reduce the 33998 power dissipation.
The 33998 also provides a 2.
6 V linear standby regulator and two 5.
0 V sensor supply outputs protected by internal lowresistance LDMOS transistors.
There are two separat...
