MC33998, Switching Power Supply

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 reduc
