The RT8259GJ6 is a DC-to-DC switching regulator specifically designed to support general-purpose applications. It features built-in PWM control and is suitable for highly efficient DC-DC conversion from low-voltage to high-voltage systems. The RT8259GJ6 also features current limit and over-voltage protection to safeguard against electrical damage.

The RT8259GJ6 operates at a switching frequency of up to 1MHz and can be used to regulate light load and high load conditions. It features an adjustable output voltage range of 1.24V to 15.6V and supports a maximum current of 2A. The regulator provides precise output voltage stability, with no need for an external compensation network and better EMI performance.

In addition, the RT8259GJ6 offers low start-up current and low quiescent current as well as low shutdown current to reduce power consumption. It also features an adjustable soft-start time and can be configured to draw only 40µA of bias current in normal operation. It also offers a feature setting of an internal soft-start voltage, overvoltage protection (OVP), adjustable soft-start time and current limit.

The RT8259GJ6 is a general-purpose switching regulator that is suitable for voltage regulation in a wide range of applications, such as monitoring and telecommunications systems, automotive electronics, and industrial power supplies. It supports a wide operating temperature range of -40°C to +85°C and is compatible with 5V, 12V, and 24V input systems.

When used in a dual-channel system, the RT8259GJ6 reduces the size and cost of each system by eliminating the need for multiple regulators. It offers remote sequencing that enables the sequencing of two supplies to be done using the I2C bus. The RT8259GJ6 also supports a logic enable function that allows the two supplies to be switched on or off individually.

To use the RT8259GJ6, two external capacitors and an external resistor are needed to set up the output voltage and current limit. The capacitor and resistor are connected to the SENSE- and VOUT- pins respectively and set the output voltage and current levels. The RT8259GJ6 has a built-in PWM control with an adjustable modulation frequency of up to 1MHz so that the output voltage can be set and regulated accurately over time.

In summary, the RT8259GJ6 is a high-efficiency, low-cost DC-to-DC switching regulator suitable for a range of applications and powering devices such as monitoring and security systems, automotive electronics and industrial power systems. It offers low start-up current and low quiescent current as well as low shutdown current for reduced power consumption. The RT8259GJ6 also supports an adjustable soft-start time, a logic enable function and remote sequencing, making it a versatile and cost-effective voltage regulation solution.
