Description
General part information
LTC1875 Series
The LTC1875 is a high efficiency 1.5A monolithic synchronous buck regulator using a constant frequency, current mode architecture. Operating supply current is only 15µA with no load and drops to <1µA in shutdown. The input supply voltage range of 2.65V to 6V makes the LTC1875 ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.The switching frequency is internally set to 550kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications, the LTC1875 can be externally synchronized from 350kHz to 750kHz. Burst Mode operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low.The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with a 0.8V feedback reference voltage. The LTC1875 is available in a 16-lead SSOP package.ApplicationsPortable ComputersPortable InstrumentsWireless Modems
