The LTC1735-1 is a high efficiency synchronous step-down switching regulator controller optimized for CPU power applications. It features OPTI-LOOP compensation for optimized transient response across various output capacitance and ESR values.
The operating frequency is programmable and synchronizable up to 500kHz, allowing flexibility in efficiency optimization. The device includes a power good window comparator that indicates when the output is within 7.5% of its programmed value, conforming to Intel Mobile CPU Specifications.
Protection features include internal foldback current limiting, output overvoltage crowbar, and optional short-circuit shutdown. The operating current level is user-programmable via an external current sense resistor. The wide input supply range allows operation from 3.5V to 30V (36V maximum).
Available in a 16-SSOP package, this controller is suitable for surface mount applications. Its very low dropout operation with a 99% duty cycle and logic-controlled micropower shutdown (IQ < 25mA) make it ideal for power-sensitive designs.
