Description

The STBB1-A is a fixed frequency, high efficiency,

buck-boost DC-DC converter able to provide

output voltages ranging from 1.2 V to 5.5 V and

input voltages from 2.0 V to 5.5 V. The device can

operate with input voltages higher than, equal to,

or lower than the output voltage making the

product suitable for single lithium-Ion, multicell

alkaline or NiMH applications where the output

voltage is within the battery voltage range. The

integrated low-RDSon N-channel and P-channel

MOSFET switches contribute to its high efficiency.

The MODE pin allows selecting between auto

mode and forced PWM mode thus taking benefit

either of lower power consumption or best

dynamic performance. The device includes also

soft-start control, thermal shutdown and current

limit. The STBB1-A is packaged in DFN10 (3 x 3

mm).
