Description
AI
The TPS62693 device is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS62693 supports up to 800-mA load current, and allows the use of low cost chip inductor and capacitors.
The device is ideal for mobile phones and similar portable applications powered by a single-cell Li-Ion battery. Different fixed output voltage versions are available in the range from 2.2 V up to 3.3 V.
The TPS62693 operates at a regulated 3-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range.
The PFM mode extends the battery life by reducing the quiescent current to 21 µA (typical) during light load operation. For noise-sensitive applications, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high. This feature, combined with high PSRR and AC load regulation performance, make this device suitable to replace a linear regulator to obtain better power conversion efficiency.
