Advance Information Switching Power Supply with Linear Regulators
The 33997 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 3.3 V linear regulator uses an external pass transistor to reduce the 33997 power dissipation. The 33997 also provides a 3.3 V linear standby regulator and two 5.0 V sensor supply outputs protected by...
