General Description

The TD6811 is a high efficiency monolithic synchronous

buck regulator using a constant frequency, current mode

architecture. The device is available in an adjustable

version and fixed output voltages of 1.5V and 1.8V.

Supply current during operation is only 20mA and drops

to  ≤1mA in shutdown. The 2.5V to 5.5V input voltage

range makes the TD6811 ideally suited for single Li-Ion

battery-powered applications. 100% duty cycle provides

low dropout operation, extending battery life in portable

systems.Automatic Burst Mode operation increases

efficiency at light loads, further extending battery life.

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. Low

output voltages are easily supported with the 0.6V

feedback reference voltage. The TD6811 is available in

TSOT23-5  package.
