 软件简介 |
The TC115 is a high-efficiency step-up DC/DC
converter for small, low input voltage or batterypowered
systems. This device has a start-up voltage
of 0.9V and a typical supply current of 80 μA. Phase
compensation and soft-start circuitry are included onchip.
Unlike conventional PWM step-up converters,
the TC115 automatically shifts to pulse frequency
modulation (PFM) at low loads, resulting in reduced
supply current and improved efficiency.
The TC115 requires only an external diode, an inductor
and a capacitor, while supporting typical output currents
of 140 mA. Supply current is reduced to less than
0.5 μA (max) when SHDN input is brought low.
Small size, low installed cost and low supply current
make the TC115 step-up converter ideal for use in a
wide range of battery-powered systems.
