LNBH26PQR

An LNBH26PQR device is a special type of voltage regulator designed to control current and voltage flows in power systems. The device’s operation is based on a switching regulator topology and its function is to regulate voltage across a load by switching the input voltage on and off at the desired rate. This helps to maintain consistent voltage levels within the system.

The LNBH26PQR device is a two-channel, low dropout (LDO) linear regulator designed to provide up to 1.5A of output current and features a built-in standby switch. It is used in high-power applications such as industrial control systems and AC inverters, as well as in low-power applications such as portable electronics, automotive infotainment systems, and portable medical devices. The device is also well-suited for use in battery-powered devices.

The LNBH26PQR device operates by sensing the load current and adjusting the output voltage accordingly. Its regulating circuit includes an input voltage-to-current converter, a current-mode control, and an output voltage regulator. The input voltage-to-current converter converts the input voltage into a current, which is then sent to the current-mode control. This current is used to control an internal PMOS transistor, which is used to control the output voltage. The output voltage is regulated by adjusting the size of the PMOS gate driving current.

The LNBH26PQR device has an operating temperature range of -40°C to 85°C, which makes it suitable for a wide range of environmental conditions. The device also features a low standby current and a soft-start function, which helps to reduce noise, maintain system stability, and minimize power dissipation. The device features a wide input range of 1.75V to 26V, providing users with flexibility when selecting the input source.

Overall, the LNBH26PQR device is an efficient and reliable voltage regulator that can be used in a variety of power systems. With its wide input range, low standby current, and wide operating temperature range, the device is an excellent choice for applications that require tight voltage regulation and power efficiency.
