The LTC®
3406B-2 is a high efficiency monolithic synchronous
buck regulator using a constant frequency, current
mode architecture. Supply current with no load is 350µA,
dropping to <1µA in shutdown. The 2.5V to 5.5V input
voltage range makes the LTC3406B-2 ideally suited for
single Li-Ion battery-powered applications. 100% duty
cycle capability provides low dropout operation, extending
battery life in portable systems. PWM pulse skipping
mode operation provides very low output ripple voltage for
noise sensitive applications.
The switching frequency is internally set at 2.25MHz, allowing
the use of tiny surface mount inductors and capacitors.
The internal synchronous switch increases efficiency and
eliminates the need for an external Schottky diode. Low
output voltages are easily supported with the 0.6V feedback
reference voltage. The LTC3406B-2 is available in a low profile
(1mm) SOT-23 package. Refer to LTC3406 for applications
that require Burst Mode®
operation.
