The LTC3405A-1.375 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 20µA and drops to <1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3405A-1.375 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 1.5MHz, allowing the use of small surface mount inductors and capacitors.
The LTC3405A-1.375 is specifically designed to work well with ceramic output capacitors, achieving very low output voltage ripple and a small PCB footprint.
The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. The LTC3405A-1.375 is available in a low profile (1mm) ThinSOT package.
For other output voltages, refer to the LTC3405A and LTC3405A-1.5/LTC3405A-1.8 data sheets.
