The TPS61129-Q1 provides a power supply design for portable equipment and smart devices, powered by various batteries and other power supplies. The TPS61129-Q1 has a 3.5A (typical) peak switch current limit. The TPS61129-Q1 employs peak current mode control with a fixed switching frequency of 2.2MHz. Under moderate to heavy load conditions, the TPS61129-Q1 operates in pulse width modulation (PWM) mode. At light load, the device has two operating modes that can be selected through the MODE pin. One is pulse frequency modulation (auto PFM) mode to improve light-load efficiency, and the other is forced PWM mode to avoid audible noise and to improve light load ripple performance. The switching frequency can also be synchronized to an external clock. The TPS61129-Q1 implements spread spectrum modulation on the internal clock signal, significantly enhancing electromagnetic interference (EMI) performance when operating in Forced PWM mode. In addition, there is an internal soft-start time to limit the inrush current during start-up.

During shutdown, the output load is fully isolated from the input power source, and the TPS61129-Q1 only consumes a 0.1µA current to achieve long battery life.

The TPS61129-Q1 output voltage can be programmed by an external resistor divider, or is available with fixed 5.15V, 5.0V, and 3.85V options internally on the chip.

The TPS61129-Q1 offers a very small design size with a 3.0mm × 3.0mm wettable flank VSON package.
