- TPS61379-Q1 — Convertidor boost sincrónico con corriente inactiva de 25 µA
The TPS61379-Q1 is a fully integrated synchronous boost converter with load disconnect function integrated. The input voltage covers 2.3 V to 14 V, while the maximal output voltage is up to 18.5 V. The switching current limit is 2 A typical. It consumes 25-µA quiescent current from VIN.
The TPS61379-Q1 employs the peak current mode control with the switching frequency programmable from 200 kHz to 2.2 MHz. 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.
The TPS61379-Q1 has various fixed output voltage versions to save the external feedback resistor. It supports the external loop compensation so that the stability and transient response can be optimized at wider VOUT/VIN ranges. It also integrates robust protection features including the output short protection, output overvoltage protection, and thermal shutdown protection. The TPS61379-Q1 is available in a 3-mm × 3-mm 16-pin QFN package with wettable flank.
