AP7332-1218FM-7 is a family of regulated power supply devices that typically provide a regulated low-voltage output from an unregulated high-voltage input, and are part of the power management integrated circuits (PMICs), voltage regulators, and linear category. It is a linear, non-switching, highly efficient boost converter ideal for small-scale power supply applications.

AP7332-1218FM-7 has a range of input voltage from 2.5 to 18V, mobile phone special version 3.7-13V and CMOS version from 2.5-5.5V, thus providing flexibility and allowing the device to be used in a wide variety of applications. The output voltage is adjustable from1.2V to 14V. It has two adjustable current limits, high and low, that allow flexibility and protection against overload. The device also has a wide operating temperature range and is designed to meet most international safety standards.

The working principle behind the AP7332-1218FM-7 is simple. The input voltage is compared with a feedback voltage which is generated from an integrated feedback divider resistor network. When the input exceeds the regulated output, the integrated error amplifier and PWM modulator control the output power switch to remain on until the output voltage is satisfied. When the output exceeds the regulated output, the integrated error amplifier and PWM modulator will turn off the output power switch until the output voltage is satisfied. The integrated PWM modulator increases the on-time of the output power switch, which increases the inductor current, until the output voltage is satisfied. The AP7332-1218FM-7 will then retain the output voltage at the controlled level by continuously adjusting the output power switch on-time.

AP7332-1218FM-7 is a versatile solution that is suitable for many linear power supply applications, such as mobile phones, digital cameras, PDAs, set-top boxes, and smart meters. The device is ideal for applications where low noise, high efficiency, small size, and flexibility are critical, especially for applications that require intermediate voltage outputs that cannot be supplied with other Voltage Regulators. The device’s wide range of features includes high efficiency, low dropout voltage, low noise and ripple level, flexibility of input voltage and adjustable output voltage, high current output capability, programmable low and high current limits, and an adjustable soft start that prevents inrush current. It also supports several protection features, including input under-voltage lockout, current-limit protection, thermal shutdown, and over-temperature protection.

AP7332-1218FM-7 is a high-performance Voltage Regulator designed to provide robust performance in a wide range of applications. Its wide range of features, along with its superior performance, make it an ideal solution for many linear power supply applications.
