Add To BomTPS61378QWRTERQ1 General Description
The TPS61378-Q1 is a fully-integrated synchronous boost converter with an integrated load disconnect function. The input voltage covers 2.3 V to 14 V while the maximal output voltage covers up to 18.5 V. The switching current limit is programmable from 1 A to 4.8 A. The device consumes 25-µA quiescent current from VIN.
The TPS61378-Q1 employs 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 loads. 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 TPS61378-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 TPS61378-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 output short protection, output overvoltage protection, and thermal shutdown protection. The TPS61378-Q1 is available in a 3-mm × 3-mm 16-pin QFN package with wettable flank.
