IP1203 – DC DC Switching Regulators
The IP1203 is a DC DC switching regulator from the family of Power Management Integrated Circuits (PMIC). This device offers high efficiency and very low voltage operation and is therefore a popular choice for battery-powered applications. It is capable of delivering up to 8 amps of output current in a compact 5mm X 7mm package. The device’s switching frequency is adjustable, allowing the user to optimize their design for efficiency or other performance criteria.
Applications
The IP1203 is especially suited for low-voltage, battery-powered applications such as those found in wearables, portable devices, and handheld equipment. It is also suitable for powering GPS systems, displays, radios, and audio equipment that require a highly efficient, low quiescent current power source. There is an internal logic control circuit on the device, which allows it to be interfaced with microcontrollers, allowing for power profile customization or quick shutdown.
Working Principle
The IP1203 DC DC switching regulator is a buck (step-down) converter, meaning it takes an input voltage and steps it down to a lower output voltage. It uses pulse width modulation to control power output. This involves rapidly switching the transistor on and off, creating pulses of voltage which control the output voltage. The width of the pulses determines the output voltage as they are averaged out over time to output DC at the desired level.
The device can be operated in either continuous or discontinuous mode. In continuous mode, the transistor is never allowed to turn off completely, leading to efficiency losses. In discontinuous mode, the transistor is allowed to cycle on and off, resulting in higher efficiency. Adjusting the switching frequency allows the user to optimize the device for a particular application.
The IP1203 is also capable of dynamic voltage scaling, which allows it to adjust the output voltage on the fly in order to regulate power. This allows it to adjust the output voltage in real time for a specific load, resulting in higher efficiency. The device also features built-in protection features such as overvoltage, overcurrent and thermal shutdown functions to ensure reliable operation.
Conclusion
The IP1203 is a low-voltage DC DC switching regulator from the family of Power Management Integrated Circuits (PMIC). It is well suited for battery-powered applications and is capable of delivering up to 8 amps of output current in a 5mm X 7mm package. The device operates using pulse width modulation and can be operated in either continuous or discontinuous mode for efficiency optimization. It also features features such as dynamic voltage scaling, overvoltage, overcurrent and thermal shutdown protection for reliable operation.
