Overview
LT1612 U DESCRIPTIO s Operates from Input Voltage As Low As 2VsInternal 0.
7AThSeyLnTc®hr1o6n1o2usisSawnit8c0h0eksHz, synchronous step-down DC/ DC converter that operates from an input voltage as low sUses Ceramic Input and Output Capacitorss as 2V.
Internal 0.
45Ω switches deliver output currents up 620mV Reference Voltages to 500mA, and the 800kHz switching frequency allows the 800kHz Fixed Frequency SwitchingsProgrammabuleseBoufrstmMalol,dleowOpvearluaetiocneramic input and output capaci- tors.
Input voltage ranges from 5.
5V down to 2V and s Low Quiescent Current: 160µA s 8-Lead MSOP or SO Package output voltage can be set as low as the 620mV reference.
The device features Burst Mode TM operation, keeping efficiency high at light loads.
Burst Mode operation can be APPLICATIO SUFEATURES defeated by pulling the MODE pin high, enabling constant switching throughout the load range for low noise.
