The LTC
3406B-1.2 is a high efficiency monolithic syn-
chronous buck regulator using a constant frequency,
current mode architecture. Supply current with no load is
300A dropping to <1A in shutdown. The 2.5V to 5.5V
input voltage range makes the LTC3406B-1.2 ideally suited
for single Li-Ion battery-powered applications. 100% duty
cycle provides low dropout operation, extending battery
life in portable systems. PWM pulse skipping mode opera-
tion provides very low output ripple voltage for noise
sensitive applications.
Switching frequency is internally set at 1.5MHz, allowing
the use of small surface mount inductors and capacitors.
The internal synchronous switch increases efficiency and
eliminates the need for an external Schottky diode. The
LTC3406B-1.2 is available in a low profile (1mm) ThinSOT
package.
