Maxim Integrated MAX628CSA+ Voltage Regulator

The MAX628CSA+ is a high-efficiency, low-power, step-up DC-DC voltage converter designed and manufactured by Maxim Integrated. This component is an ideal choice for battery-powered applications where extended battery life is crucial. With its ability to convert lower voltage inputs to higher voltage outputs, the MAX628CSA+ is well-suited for devices that require a stable power supply despite fluctuating or sub-optimal input voltages.

Encased in a compact 8-pin SOIC package, the MAX628CSA+ offers a space-saving solution for modern electronic devices. The device is capable of delivering an adjustable output voltage, which can be set by the user with external resistors. This flexibility makes it easy to tailor the output to meet the specific needs of various applications, such as powering LCD panels, PDAs, and portable communication devices.

The MAX628CSA+ operates over a wide input voltage range, starting as low as 2V and up to 16.5V, allowing it to accommodate multiple battery chemistries and configurations. Its high switching frequency of 1.4MHz minimizes the size of external components, particularly the inductor and capacitors, further contributing to a reduced overall footprint and cost-effectiveness for the end product.

One of the standout features of the MAX628CSA+ is its high efficiency, which can reach up to 87%. This is achieved through its low quiescent current and the use of a pulse-frequency modulation (PFM) control scheme that reduces the switching losses at light loads. Additionally, the device includes a thermal shutdown feature and current limit protection, enhancing the safety and reliability of the applications it powers.

In summary, the Maxim Integrated MAX628CSA+ step-up DC-DC converter is a versatile and efficient solution for a wide range of portable electronics. Its adjustable output, wide input voltage range, and high-frequency operation make it an excellent choice for designers looking to optimize power management in compact, battery-operated devices.
