LTC3701EGN#PBF 产品详情

The LTC3701EGN is a 2-phase dual constant frequency current mode step-down DC/DC controller providing excellent load and line regulation. Power loss and noise due to ESR of the input capacitor are minimized by operating the two controller output stages out-of-phase.

The LTC3701EGN provides a 0.8V ±2% voltage reference and consumes only 460µA of quiescent current. To further maximize the life of a battery source, the external P-channel MOSFET is turned on continuously in dropout (100% duty cycle).

Switching frequency is internally set at 550kHz, allowing the use of small inductors and capacitors. For noise sensitive applications, the LTC3701EGN can be externally synchronized using its phase-locked loop. The frequency can also be externally set from 300kHz to 750kHz by applying a voltage to the PLLLPF pin. Burst Mode operation is inhibited during synchronization or when the EXTCLK/MODE pin is pulled low to reduce noise and RF interference.

The LTC3701EGN contains independent internal soft-start circuitry for each controller. Other features include a power good output voltage monitor and output overvoltage and short-circuit protection.

The LTC3701EGN is available in a small footprint 16-lead narrow SSOP package.
