PMIC - Voltage Regulators - DC DC Switching Regulators

TPS62315YZT is a 300mA, low-noise, low-dropout (LDO) voltage regulator with integrated switch mode power supply (SMPS) from Texas Instruments that operates from 1.5V to 5.5V input voltage. It supports synchronous buck-boost operation with input/output voltages ranging from 0.8V to 5.5V. It achieves a typical dropout of 300mV at 200mA, making it suitable for battery-powered applications.The device offers a wide array of features, such as programmable output voltage sequencing, current limiter, soft-start and thermal shutdown. It also offers an adjustable output voltage with tolerance ranges from ±1% to ±7%. Additional protection against ESD, reverse current, over temperature and current limit ensures longer battery lifetimes and a lower average on-resistance.TPS62315YZT also offers unique features such as a programmable maximum boost voltage limit and external voltage set pin for autonomous regulation of the input voltage.The device is well-suited for PoE (power over Ethernet) and battery-powered applications, such as industrial automation, internet of things (IoT), communication infrastructure, medical systems, wearables and portable and handheld equipment.Working PrincipleThe TPS62315YZT contains a low dropout (LDO) voltage regulator, switching power supply and a high-side and low-side FET switch. It operates in buck-boost mode, allowing both buck and boost configurations and permitting input/output voltages above and below the input voltage.The TPS62315YZT can be configured in either a buck or a continuous boostmode. In continuous buck mode, the FET switches are placed in parallel and the device acts as a typical buck regulator, while in continuous boostmode, the FET switches form a standard boost circuit, with the inductor current flowing forward when the input voltage is greater than the output voltage.The device has an operating range of 1.5V to 5.5V and can source up to 300mA of output current. The device also features a power-good indicator and a programmable power-on and power-off sequence.The device also includes an adaptive control system, which automatically adjusts the regulating voltage by intelligent compensation and reduces the voltage ripple on the output voltage. The device also offers programmable soft-start and current limit, and provides a precision of ±1% of the output voltage, allowing the user to implement a precision voltage control system.ConclusionThe TPS62315YZT is a low-dropout integrated switch mode power supply that can source up to 300mA of output current. The device can be configured in either buck or continuous boost mode, and offers wide features such as programmable output voltage sequencing, current limiter, soft-start, adaptive control and thermal shutdown. It is well-suited for PoE and battery-powered applications, such as industrial automation, communication infrastructure and medical systems.
