LTC3735EUHF

Special Purpose Regulators Overview

The LTC3735EUHF is a two-phase, high-efficiency DC/DC controller designed for Intel mobile CPUs. It operates with an input voltage range supporting wide input sources and provides a single output adjustable from 700mV to 1.71V. The device features a switching frequency range of 210 kHz to 550 kHz and maintains a quiescent current of 20 uA. It is housed in a 38-lead QFN (5x7) package with an exposed pad, suitable for surface mount installation.

Special Purpose Regulators Procurement Notes

Verify the specific suffix (EUHF#PBF) against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure compatibility with Intel mobile CPU specifications before integration. Check RoHS compliance status via the manufacturer's datasheet. Confirm availability through authorized distributors as supply levels may vary.

Special Purpose Regulators Selection Notes

Select this component when designing power stages for Intel mobile processors requiring two-phase control. Consider the 38-QFN package for space-constrained layouts. Evaluate the 210 kHz to 550 kHz frequency range against EMI requirements and inductor size constraints. Verify that the 20 uA quiescent current meets standby power targets.

Special Purpose Regulators Part Context

The LTC3735 series comprises synchronous buck controllers optimized for mobile computing platforms. The EUHF variant denotes a specific lead-free, halogen-free package type within the Linear Technology portfolio. These controllers manage multiple phases to deliver high current densities while maintaining thermal performance in compact form factors typical of laptop and tablet designs.

Special Purpose Regulators Replacement Considerations

Compatible variants include LTC3735EG#TRPBF and LTC3735EUHF#TRPBF. Verify package equivalence and tape-and-reel versus tube packaging requirements. Cross-reference electrical parameters to ensure functional interchangeability in existing Intel mobile CPU designs.
