The MAX7645BCWP+ is a high-efficiency, current-mode PWM step-up (boost) dc-dc controller integrated circuit (IC) component. It is designed to provide a regulated output voltage from low input voltages, making it ideal for various applications that require voltage boosting.
The IC operates over a wide input voltage range of 2.5V to 16V, allowing flexibility in selecting input sources. It can deliver output voltages up to 28V and is capable of providing up to 150mA of load current. The MAX7645BCWP+ offers high efficiency, typically up to 89%, ensuring efficient power conversion.
One of the key features of this IC is its current-mode control architecture, which provides fast transient response and excellent stability over a wide range of load conditions. It also offers an adjustable switching frequency ranging from 100kHz to 500kHz, enabling users to optimize for efficiency or minimize component size.
The MAX7645BCWP+ incorporates a soft-start feature that limits inrush current during startup, preventing excessive stress on the input power source and the components in the system. It also includes integrated power sequencing, allowing multiple ICs to be powered up in a controlled manner.
This IC component provides robust protection features to ensure system reliability. It includes overvoltage protection (OVP) and undervoltage lockout (UVLO) functions, safeguarding the load and the IC from voltage spikes and undervoltage conditions
