Package Type

General Description

The TC110 is a step-up (Boost) switching controller

that furnishes output currents of up to 300mA while

delivering a typical efficiency of 84%. The TC110

normally operates in pulse width modulation mode

(PWM), but automatically switches to pulse frequency

modulation (PFM) at low output loads for greater

efficiency. Supply current draw for the 100kHz version

is typically only 50

µA, and is reduced to less than

0.5

µA when the SHDN input is brought low. Regulator

operation is suspended during shutdown. The TC110

accepts input voltages from 2.0V to 10.0V, with a

guaranteed start-up voltage of 0.9V.

The TC110 is available in a small 5-Pin SOT-23A

package, occupies minimum board space and uses

small external components (the 300kHz version allows

for less than 5mm surface-mount magnetics).
