Introduction on TPS40211QDGQRQ1 DC DC Switching Controllers

The TPS40211QDGQRQ1 DC DC switching controller from Texas Instruments is a monolithic, pulse-width-modulated (PWM) controller designed for efficient DC-to-DC conversion solutions. It is designed to minimize external components, minimize losses, and maximize system efficiency in limited space. Its capability to operate at a wide range of frequencies across different load conditions makes it suitable for use in a wide range of applications.

Applications of TPS40211QDGQRQ1 & Its Working Principle

The TPS40211QDGQRQ1 DC-DC switching controller is ideal for applications requiring high efficiency, low voltage bias, and small footprint such as:

• Automotive applications, such as 12-volt lead acid battery charging systems.
• Portable and consumer electronics, such as cameras, game consoles, and MP3 players.
• Telecommunications systems, such as cellular phones.

The TPS40211QDGQRQ1 DC-DC switching controller operates using a hysteretic control scheme for improved light load efficiency. This scheme avoids output voltage ripple, eliminates current-mode control long periods of deadtimes and requires no loop compensation. The device has an integrated N-Channel MOSFET driver circuit capable of operating at up to 100kHz frequencies and supports up to 30V MOSFETs for up to 30W power conversion. The TPS40211QDGQRQ1 DC-DC switching controller also features an adjustable oscillator frequency and enable/disable control pins to support several dimming and enable/disable control modes. The enable/disable control pin is an active-low function. Additionally, built-in power good indicators (ACTIVE LOW) and turn-off time t_OFF time are included.

Layout and Feature Summary of TPS40211QDGQRQ1

The TPS40211QDGQRQ1 DC-DC switching controller is a 6.5mm x 6.5mm, 32-pin HVSSOP (still-small-outline package) package with a die-cast exposed pad for efficient heat transfer. Its quiescent supply current is typically <10 Microamps and its shutdown current is typically <2 Microamps, reducing power waste and cost. The TPS40211QDGQRQ1 DC-DC switching controller features an open-drain power-good (ACTIVE LOW) indicator output and adjustable tON_MIN minimum off-time to eliminate current-mode control during light-load conditions. The device also features over-voltage, under-voltage, and over-temperature protection to provide a safe and power-efficient solution for various applications.

Conclusion

The TPS40211QDGQRQ1 DC-DC switching controller from Texas Instruments is a monolithic, pulse-width modulated (PWM) controller designed for efficient DC-to-DC conversion solutions and is suitable for use in a wide range of applications. It features an integrated N-Channel MOSFET driver circuit capable of operating at up to 100kHz frequencies, adjustable oscillator frequency, enable/disable control pins, open-drain power-good (ACTIVE LOW) indicator output, adjustable tON_MIN minimum off-time, over-voltage, under-voltage, and over-temperature protection. The device is packaged in a 6.5mm x 6.5mm, 32-pin HVSSOP package with a die-cast exposed pad for efficient heat transfer and its quiescent and shutdown supply current are typically <10 microamps and <2 microamps respectively, making it perfect for high efficiency, low voltage bias, and small footprint applications such as automotive, portable and consumer electronics, and telecommunications systems.
