DESCRJPTION
The TP3308 is a constant frequency, current mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency. The 2.0V to 6.5V input voltage range makes the TP3308 ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery or 3-cell NiMH/ NiCd batteries. The output voltage can be regulated as low as 0.6V. The TP3308 supports up to 800mA load current and can also run at 100% duty cycle for low dropout applications, extending battery life in portable systems.
Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductor and capacitors. The internal synchronous switch increases efficiency while eliminate the need for an external Schottky diode. The TP3308 is available in a low profile 5 lead SOT23-5 package.
