TPS61088/TPS61088-Q1 Synchronous Boost Converter

Texas Instruments TPS61088/TPS61088-Q1 Fully Integrated Synchronous Boost Converters are fully integrated converters with a power switch and rectifier switch. This provides a high efficiency and small size solution in portable systems. The TPS61088/TPS61088-Q1 has wide input voltage range from 2.7V to 12V. This supports applications with single cell or two cell Lithium batteries. The device has 10A switch current capability. It is capable of providing an output voltage up to 12.6V. The TPS61088/TPS61088-Q1 from Texas Instruments uses adaptive constant off-time peak current control topology to regulate the output voltage. In moderate to heavy load condition, it works in the pulse width modulation (PWM) mode. In light load condition, the device has two operation modes selected by the MODE pin. One is the pulse frequency modulation (PFM) mode to improve the efficiency. The other one is the forced PWM mode to avoid application problems caused by low switching frequency. The switching frequency in the PWM mode is adjustable ranging from 200kHz to 2.2MHz by an external resistor. The TPS61088-Q1 devices are AEC-Q100 qualified for automotive applications.
