ADP2116ACPZ-R7

The ADP2116ACPZ-R7 is a highly versatile and efficient synchronous step-down DC-to-DC converter designed to meet a wide range of power conversion requirements. This device offers dual or single output configurations, high power density, and advanced protection features, making it ideal for applications in telecommunications, networking, consumer electronics, industrial control, and medical equipment.

Key Features:

1. Configurable Outputs:

   • Dual Output: The ADP2116ACPZ-R7 can be configured to provide two independent outputs, each capable of delivering up to 3A of current. Alternatively, the outputs can be set to 3A and 2A, offering flexibility in meeting different load requirements.

   • Single Output: For applications requiring higher current, the two channels can be combined to provide a single interleaved output capable of delivering up to 6A of current. This configuration reduces input ripple current and input capacitance, enhancing overall system performance.

2. High Efficiency:

   • The ADP2116ACPZ-R7 achieves high efficiency across a wide load range, thanks to its synchronous rectification and current mode control. This helps to reduce power loss and extend battery life in portable applications.

3. Wide Input Voltage Range:

   • The device supports an input voltage range of 2.75V to 5.5V, making it compatible with a variety of power sources, including single-cell Li-ion batteries and multiple-cell NiMH or alkaline battery packs.

4. Adjustable Output Voltage:

   • The output voltage of each channel can be independently set to one of several fixed values (0.8V, 1.2V, 1.5V, 1.8V, 2.5V, or 3.3V) using external resistors. Alternatively, the output voltage can be adjusted to as low as 0.6V using a resistor divider network.

5. High Switching Frequency:

   • The ADP2116ACPZ-R7 operates at a switching frequency of up to 2MHz, enabling the use of smaller, lower-cost inductors and capacitors. This reduces the size and cost of the power supply circuit.

6. Advanced Protection Features:

   • The device incorporates a range of protection features, including under-voltage lockout (UVLO), over-current protection (OCP), over-temperature protection (OTP), and short-circuit protection. These features help to ensure safe and reliable operation of the converter.

7. Flexible Operation Modes:

   • The ADP2116ACPZ-R7 can be configured to operate in pulse-skipping mode at light loads to improve efficiency. Alternatively, it can be set to operate in forced PWM mode for applications that are sensitive to noise.

8. Compact Package:

   • The device is packaged in a compact 32-lead LFCSP package, measuring just 5x5mm. This small footprint makes it easy to integrate into space-constrained applications.

Applications:

The ADP2116ACPZ-R7 is well-suited for a wide range of applications, including:

• Point-of-Load (POL) Regulation: Providing efficient power conversion for microprocessors, FPGAs, DSPs, and other high-performance digital circuits.

• Telecommunications and Networking: Powering line cards, routers, switches, and other telecommunications equipment.

• Consumer Electronics: Supplying power to portable devices such as smartphones, tablets, digital cameras, and other battery-powered electronics.

• Industrial Control: Providing power for sensors, actuators, and other industrial control components.

• Medical Equipment: Supplying power for patient monitors, portable ultrasound machines, and other medical diagnostic equipment.

In summary, the ADP2116ACPZ-R7 is a highly versatile and efficient DC-to-DC converter that offers dual or single output configurations, a wide input voltage range, adjustable output voltage, high switching frequency, advanced protection features, and a compact package. These features make it an ideal choice for a wide range of power conversion applications.
