The LT8609BEMSE#TRPBF is a synchronous dual-output step-down switching regulator in an 8-pin 3mm x 3mm QFN package. It is an advanced DC-DC regulator, specifically designed for the challenging task of providing dual, independent and ultra-clean power supplies in demanding mobile and low-power applications. The device is designed to be easily configured for many different applications, and has unusually low quiescent current to extend battery life. It is particularly suitable for powering a wide range of image sensors from a single supply, Low Noise Micropower Processor, Memory and RF applications.

The LT8609BEMSE#TRPBF is a simple and low component count controller that enables cost-effective, highly efficient point of load (POL) power supply designs. The device integrates PWM current-mode control for the optimal combination of transient response, frequency response, and noise immunity. It takes an input voltage range of 2.5V to 5.5V and delivers up to 1A of output current. The integrated dual output control circuitry provides two separate independent outputs that can handle up to 1A of current and supports output voltages up to 5V.

The LT8609BEMSE#TRPBF uses an integrated synchronous rectifier, requiring no external Schottky diodes and reducing component count, as well as minimizing total solution size and cost. An optional pin controls the turn-off timing of the integrated FET switch, enabling flexibility and simplifying the power solution design. The internal product safety features include cycle-by-cycle current limit and over-temperature protection. The device also features frequency fold-back, allowing the user to select the right frequency for optimized efficiency, versus size.

The LT8609BEMSE#TRPBF is ideal for a wide range of applications such as, but not limited to: imaging, low-noise Micropower Processors, memory, RF, and internet of things, as it provides two independent, tightly regulated outputs while also taking up very little space.

The LT8609BEMSE#TRPBF operates with feedback voltage mode, which allows it to precisely control and regulate the output voltage for any load application. It uses a voltage mode architecture, sensing the output voltage via an external dividers that feed into a control loop. If there is a disturbance in the output voltage, the control loop compensates by adjusting the duty cycle of the PWM control circuitry to maintain regulation and respond swiftly to changes in load or line conditions.

The device also has a few built-in protection features that ensure the system will work reliably and properly. The LT8609BEMSE#TRPBF contains an over-temperature protection (OTP) circuit that will sense when the die temperature rises too much, and turn off the device when it detects such a condition. It also contains a cycle-by-cycle current limit circuit with fold-back, which will reduce the output current if an overload condition is detected. Finally, the device features an optional frequency fold-back control, allowing the user to select the right frequency for optimized efficiency versus size.

The LT8609BEMSE#TRPBF is the perfect solution for powering a wide range of image sensors from a single supply or for powering low noise Micropower Processors, memory, and RF applications. With low component count and integrated synchronous rectifier, the LT8609BEMSE#TRPBF ensures high efficiency designs and cost-effective power solutions. Furthermore, its integrated protection features ensure the device will operate reliably and properly in any application.
