LINEAR TECHNOLOGY LTC1707 Manual

Update: 30 September, 2023

The LTC ®1707 is a high efficiency monolithic current mode synchronous buck regulator using a fixed frequency architecture. The operating supply range is from 8.5V down to 2.85V, making it suitable for both single and dual lithium-ion battery-powered applications. Burst Mode op- eration provides high efficiency at low load currents. 100% duty cycle provides low dropout operation, extend- ing operating time in battery-powered systems. The switching frequency is internally set at 350kHz, allowing the use of small surface mount inductors. For noise sensitive applications it can be externally synchro- nized up to 550kHz. Burst Mode operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low preventing low frequency ripple from interfer- ing with audio circuitry. Soft-start is provided by an external capacitor. The internal synchronous MOSFET switch increases effi- ciency and eliminates the need for an external Schottky diode, saving components and board space.
