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.
