The ADP5070AREZ is a monolithic switching regulator DC-DC power supply IC. It is used to regulate the output voltage for a wide range of applications, primarily in portable digital and analog devices. The ADP5070AREZ provides an efficient and cost effective solution for these applications.

Application Field

The ADP5070AREZ can be used for step up, step down, and voltage inverting. This makes the ADP5070AREZ suitable for applications such as charge pumps, RF power amplifiers, cellular phone chargers, portable CD/DVD players and laptop power supplies. It is also ideal for power management systems in portable electronic devices.

The ADP5070AREZ’s small size and low power consumption (less than 5μA in shutdown mode) make it an ideal choice for battery-operated applications. The ADP5070AREZ has a wide input voltage range (3V to 18V) and is capable of delivering up to 2A of output current. It features a low-noise, green-mode switching frequency, which makes it ideal for CCD and image sensor applications.

The ADP5070AREZ is designed to handle over-temperature and over-current conditions, ensuring safe operation at high temperatures and under extreme working conditions. The device also offers a wide operating temperature range, from -40°C to +85°C.

Working Principle

The ADP5070AREZ is a voltage regulator, designed to convert an input voltage to a fixed output voltage. It operates by switching on and off a power MOSFET, converting the input voltage to a controlled voltage. The power MOSFET is controlled by a pulse width modulated signal, generated by an internal pulse width modulator oscillator. The pulse width modulator operates at constant frequency and maintains a regulated output voltage.

The ADP5070AREZ operates in either a step-up or step-down mode, depending on the voltage difference between the input and output. If the output voltage is higher than the input, the device switches in the step-up mode and stores energy in an internal inductor. This energy is then transferred to the output in the form of a regulated output voltage. If the output voltage is lower than the input, the device switches in the step-down mode and delivers a regulated output voltage.

The ADP5070AREZ also features soft-start, over-current protection (OCP), over-temperature protection (OTP), and an integrated voltage reference (VREF). The OCP and OTP functions protect the device from damage due to excessive current or temperature. The VREF feature allows for more accurate regulation of the output voltage.

The ADP5070AREZ is a cost-effective and highly efficient switching regulator, making it ideal for portable electronic devices and other low power applications. It offers a low quiescent current and wide input voltage range, while providing over-current and over-temperature protection to ensure safe operation in extreme conditions.
