Manufacturer Part Number
TS3410CX5RF
Description
1A / 1.5MHz Synchronous Buck Converter
Manufacturer
TSC [Taiwan Semiconductor Company, Ltd]
Datasheet
General Description
TS3410 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode
architecture. The device is available in an adjustable version. Supply current with no load is 350uA and drops to <1uA
in shutdown. The 2.5V to 6.5V input voltage range makes TS3410 ideally suited for single Li-Ion, two to four AA
battery-powered applications. 100% duty cycle 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.
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 decreases need of an external Schottky diode. Low output
voltages are easily supported with the 0.6V feedback reference voltage.
