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
A, and is reduced to less than
0.5
A 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).
