Description

The LTC®3404 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 10mA and drops to < 1A in shutdown. The 2.65V to 6V input voltage range makes the LTC3404 ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.

Switching frequency is internally set at 1.4MHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications the LTC3404 can be externally synchronized from 1MHz to 1.7MHz. Burst Mode operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low, preventing low frequency ripple from interfering with audio circuitry.

The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.8V feedback reference voltage. The LTC3404 is available in a space saving 8-lead MSOP package.

For higher input voltage (11V abs max) applications, refer to the LTC1877 data sheet.
