TPS659121YFFT Working Principle

The TPS659121YFFT PMIC incorporates an advanced power control technology that enables it to provide consistent, stable, and optimized power delivery. This technology uses two main methods to control and regulate the power delivery: Pulse Width Modulation (PWM) and High-Frequency Fixed Frequency (HFFF). The PWM approach, in which the duty cycle of a pulse is modulated to generate output, is often used for high-current applications and allows for high-efficiency operation. The HFFF approach utilizes a fixed frequency, high-frequency power switching technique, which switches the power between on and off cycles in order to provide more accurate and consistent power delivery.

Additionally, the TPS659121YFFT PMIC includes an advanced power management logic that manages the power delivery across multiple system components, including micro-controllers, sensors, and other power-hungry components. This advanced power management logic allocates power among components in a manner that increases efficiency and eliminates power waste. Additionally, the device includes an integrated multiple-output power sequencer, enabling set-up and shut-off operations, as well as sequencing between different power levels.
