The SC2602STRB is a DC/DC step-up switching controller designed only for use in mobile consumer and automotive products. The controller provides supervisory and operational control, as well as support of system power management and low power consumption, which reduces the cost of switching regulators and simplifies their design. This device consumes only 680nA in all power-down modes and is thus very power efficient.

The primary application field of the SC2602STRB involves systems that power components that require a 3V to 60V input voltage range. Such applications include Bluetooth speakers, monitor reflectors, car alarms, multimedia, embedded systems, and any system that requires a reliable and adjustable power source.

The device features an internal 5V LDO, which eliminates the need for an external voltage regulator for a 5V supply for the logic. Its 1.5MHz switching frequency allows for small output filter inductors, and its PWM/PFM control modes provide a balance between efficiency and system noise.

The SC2602STRB incorporates a variety of protection and safety mechanism, such as input voltage overshoot protection, UVLO, open loop protection, and two thermal shutdowns, which protect the system from damages due to excessive current and voltage. The internal gate driver also eliminates the need for an external driver, making the device more cost-effective.

The working principle of the SC2602STRB is based on pulse-width modulation (PWM) and pulse-frequency modulation (PFM) control. In PWM mode, the switching frequency and duty cycle are adjusted according to the output voltage, resulting in a stable and controlled output voltage. In PFM mode, the controller switches on and off depending on the input voltage and output current, resulting in more energy savings. The current mode and temperature compensation allows the optimum performance during temperature fluctuations and input voltage fluctuations.

The SC2602STRB DC/DC switching controller is an excellent solution for a range of applications requiring a step-up switching regulator. The device’s low power consumption, protection and safety features, and adjustable working modes make it the ideal choice for a variety of devices and systems.
