TPS60101

illustrate

The TPS60101 boost, regulated charge pump produces 3.3-V ± 4%, from 1.8 V output voltage to 3.6 V input voltage (two alkaline, nickel-cadmium, nickel-metal hydride batteries or). The output current is 100 from 2 to V input current. Only 4 external capacitors are required to build a complete low-noise DC/DC converter. The push-pull two-ended single-ended charge pump operating mode ensures that low output voltage ripple is continuously transferred to the output for flow. From the 2 - V input, TPS60101 can begin to enter full load with loads as low as 33Ω.

The main feature of the TPS60101 is that there is a fixed frequency mode to reduce noise and output voltage ripple or a power-saving pulse jump mode at light loads and extend battery life. The TPS60101 has a switching frequency of 300 kHz.
