The LP5910-1.8DRVT is a highly efficient, low-Iq, ultra-small step-down DC/DC converters. It is part of the Linear PMIC - Voltage Regulators family, specifically designed for battery-powered applications like tablets, smartphones, and wearables. The device consists of an integrated gate driver, an internal power switch, and an internal compensation network, as well as current and thermal protection functions. It offers excellent transient performance, stability, and efficiency in an ultra-small form factor.

The LP5910-1.8DRVT offers a wide input voltage range from 4.5V to 36V and support output voltages from 0.6V to 5V. Additionally, it features an adjustable switching frequency from 300kHz to 2MHz, to allow for the most flexible design. The device also supports current-mode pulse-width modulation (PWM) and utilizes an external compensation network to optimize the device’s performance.

The LP5910-1.8DRVT offers precise voltage regulation with line-load regulation of 0.42% (typ. 0.2%, MAX 0.5%). It also offers efficient on-time control, high frequency switching capability with low ripple, and fast transient response.

The LP5910-1.8DRVT has features to protect the device from current, voltage, and thermal overloads, as well as reverse-battery protection and under-voltage lockout for improved safety. The device also includes a dedicated sleep-mode pin to reduce no-load quiescent current, and an available shutdown pin for system-level shutdown control.

The LP5910-1.8DRVT can also be used in a multi-phase configuration to boost output current and efficiency, while still operating in an ultra-small space. The device also integrates input and output capacitors, eliminating the need for external DC filter components and reducing total BOM cost.

The LP5910-1.8DRVT is suitable for battery-powered applications like smartphones, tablets, wearables, industrial, and consumer electronics. It\'s supported by many design tools, and evaluation kits are available to speed the design process.
