The TPS61232DRCT is a High Efficiency Synchronous Step-up Converter with 5A switch optimized for products powered by a one-cell Li-ion battery or a regulated power rail of 3.3V. The device is based on a quasi-constant on-time valley current mode control scheme. The typical operating frequency is 2MHz, which allows the use of small inductors and capacitors to achieve a small solution size. The TPS61232 provides a fixed output voltage of 5V. During light loads, it automatically enters power save mode for maximum efficiency at lowest quiescent currents. In shutdown, the load is completely disconnected from the input and the input current consumption is reduced to 1.5µA typical. The device integrates a precise low power EN comparator. The EN threshold as well as the hysteresis of the enable comparator are adjustable with external resistors and support application specific system power up and down requirements.
