SC1189
Product is not recommended for new design.
The SC1189 combines a synchronous voltage mode controller with two low-dropout linear regulators providing most of the circuitry necessary to implement three DC/DC converters for powering advanced microprocessors such as Pentium®III.
Features
- Synchronous design, enables no heatsink solution
- 95% efficiency (switching section)
- 5-bit DAC for output programmability
- Designed for Intel Pentium® III requirements
- 1.25 V, 2.5 V short-circuit-protected linear controllers
- Linear controllers adjustable to 1.8 V chipset.
- VRM 8.5 Compliant
- VRM 8.4 Compliant (1.3 V to 1.8 V)
- 1.0% accuracy (1.6 V to 1.8 V)
- On-chip power-good signal
- Available in Lead free package, fully WEEE and RoHS compiant
- Pentium® III microprocessor supplies
- 1.050 V to 1.825 V microprocessor supplies
- Programmable triple power supplies
