DA9217

AI生成コンテンツ: The document details the register default settings and configurations for the DA9217-17V7x OTP variant, a single-channel dual-phase buck converter with a maximum output voltage of 1.90 V. It covers key parameters such as operation modes, slew rates for startup and shutdown, current limits, and chip configuration features. The document includes variant ordering information, I2C slave addresses for different CONF pin states (Low, High, Hi-Z), and comprehensive register settings for each state. It also defines terms like GPIO, OTP, DVC, and WLCSP, providing a technical foundation for device integration and configuration.

AI生成コンテンツ: Output voltage above 1.9 V for DA9217/DA9220/DA9121/DA9122 is achieved by using external resistors and capacitors. These devices operate within an input voltage range of 2.5 V to 5.5 V and support configurable output voltage from 0.3 V to 1.9 V natively. By applying a resistive divider and recommended external components, the output voltage can be adjusted beyond 1.9 V. The document provides recommended component connections, waveform results, and register settings to realize this higher output voltage. It includes practical examples with input voltages of 3.7 V and 5 V, output voltages of 2 V and 3.3 V, and load currents of 3 A.
