General Description
The TD6817 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 TD6817 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 TD6817 is available in
TSOT23-5 package.
