Announced by Mouser Elecronics, Texas Instruments TPS61379-Q1 Synchronous Boost Converter is a fully integrated synchronous boost converter with load disconnect function integrated. The input voltage covers 2.3V to 14V, while the maximal output voltage is up to 18.5V. The switching current limit is 2A typical. It consumes a 25µA quiescent current from VIN. The TPS61379-Q1 employs the peak current mode control with the switching frequency programmable from 200kHz to 2.2MHz. The device works in fixed-frequency PWM operation in medium to heavy load. There are two optional modes in light load by configuring the MODE pin: auto PFM mode and forced PWM to balance the efficiency and noise immunity in light load. The switching frequency can be synchronized to an external clock. The TPS61379-Q1 uses the spread spectrum of the internal clock to be more EMI friendly at FPWM mode. In addition, there is an internal soft-start time to limit the inrush current.
