FEATURES

LDO Controller allows the use of a low cost pass

transistor for the I/O supply

8-Pin SOIC combines switching and linear

controller

Internal pre-regulator eliminates cross talk

between switching and linear regulators

Automatic shut down of the linear regulator when

connected to the Vcc2 detect pin

On-Board MOSFET Driver

Fastest transient response of any controller

method (0 to 100% Duty Cycle in 100ns)

1% Internal Voltage Reference

Internal Under-Voltage Lockout protects MOSFET

during start-up

APPLICATIONS

Dual supply low voltage processor applications,

such as: P55C, CYRIX M2, POWER PC

and AMD K6

Simple 5V to 3.3V switcher for Pentium with AGP

or Pentium II applications
