TPS40200MDREP is a DC to DC switching controller manufactured by Texas Instruments, designed for battery-powered systems in need of power management. This device, released in 2008, is a monolithic integrated circuit, where input voltages from 2.7V to 20V can be converted to output voltages from 0.8V to 15V. The voltage can then be regulated or switched in depth or PWM control modes with a wide selection of methods and protections. There is also an internal low-dropout 0.2V VREG regulator, which can be used to power the switching capability, help protect against feedback fluctuation, or act as a precision reference for external opamps.

The primary application field for the TPS40200MDREP is in handheld wireless devices, portable audio systems and digital cameras, amongst other low-power, low-voltage systems. This DC to DC switching controller makes it possible to easily leverage the use of 1 or 2 battery cells to produce +5 V and +3.3V power rails commonly needed in cell phones, while also offering low-dropout voltage regulation, fast-transitioning transient protection, and separate high-side and low-side MOSFETs.

In terms of working principle, the TPS40200MDREP device contains internal circuitry providing multiple control modes which facilitate the design’s flexibility and accurate power control. These modes include depth and PWM control, which allows the designer to manipulate the output power dependent on their applications’ needs. To increase system efficiency levels, the device is equipped with a single pulse-width modulation (PWM) control. The device also features two power FETs, a high side and a low side, which is connected to the inductor to operate in a synchronous switching configuration.

The device\'s high-side PWM drive is designed to maintain identical duty-cycles for both the high and low side, meaning that the high-side and low-side are not directly responsible for controlling the voltage. This allows for faster transition times when multiple devices are involved, allowing the power supply to be switched quickly, even when large inductance values are used.

The TPS40200MDREP also meets requirements for soft-start and over-voltage protection. With the over-voltage protection feature, the controller will detect if the output voltage is exceeding the limit and respond by quickly shutting down the switch, thereby protecting the downstream components of the power supply. This feature is especially beneficial in high-speed power supplies.

In summary, the TPS40200MDREP device is a powerful DC to DC switching controller released by Texas Instruments which has many capabilities and unique characteristics. It is suitable for applications requiring low-dropout voltage regulation, fast-transitioning transient protection, and separate high-side and low-side MOSFETs. This DC to DC switching controller also uses PWM control to increase system efficiency levels, and features two power FETs,a high side and a low side, which is connected to the inductor to operate in a synchronous switching configuration. This makes it perfect for the portable and low-voltage applications mentioned, as well as any other battery-powered system in need of power management.
