The SP6652ER-L/TR is a type of DC/DC switching regulator. It is a type of power management integrated circuit (PMIC), specifically, a voltage regulator.

The SP6652ER-L/TR is a fixed-frequency, dual-output step-down switching regulator optimized for applications that require low output ripple, low quiescent current, and precise voltage regulation over temperature. It includes two buck converters capable of providing respectable amounts of output current and implements synchronous rectification to improve efficiency. It also features enable control, pre-bias start up, power good indicator and integrated soft-start.

The device has a Programmable Current Limit that helps to safely achieve maximum power throughout the selected operating range and to prevent overheating. The device is capable of operating from input voltage sources ranging from 5 V to 32 V. The device also supports up to two output voltages and utilizes an internal temperature protection system that shuts off the device in the event of an over-temperature condition.

This SP6652ER-L/TR DC/DC switching regulator works on the principle of Pulse Width Modulation (PWM). This form of modulation is used to control the switch times and enables precise control over the output voltage, no matter what the load changes are. On the output side, the device regulates the output voltage to a precise and stable level. This is done by monitoring the sensed load current and the output voltage. When the output voltage deviates from the desired set-point, the device’s internal logic adjusts the switch times to correct the output voltage.

The device has many application fields, such as automotive and industrial, communications, and consumer electronics. In the field of automotive, it is mainly used in engine control system, powertrain and transmission control, lighting, audio and multimedia systems. In industrial applications, it is used in factory automation, power supplies, displays, and embedded applications. In communications, it is used in cable connections and terminal equipment, base stations and mobile phones. In consumer electronic applications, it is mainly used in portable computers, home appliances and medical equipment.

In a nutshell, the SP6652ER-L/TR is a highly efficient, fixed frequency, dual output step-down switching regulator with two buck converters and integrated soft-start. It is highly versatile in application fields, from automotive to consumer electronics, while offering very precise and stable voltage regulation.
