MAX1798EGP+T

The MAX1798EGP+T is an integrated, high-efficiency, and high-precision step up power converter designed for providing a regulated output voltage in low supply voltage applications. It is specially designed for low-input voltage, high noise and high ambient temperature environments. The device features a small size, low quiescent current and wide input voltage range, making it ideal for applications such as portable computing and consumer electronics.

The MAX1798EGP+T is an advanced, monolithic pulsed-mode step-up power converter specifically designed to provide regulated outputs that are highly precise. Its high-efficiency operation, low quiescent current, wide input voltage range, and small size make it ideal for use in portable and consumer products. The device includes a feedback voltage feedback loop that ensures regulated voltage accuracy of +-1.5%. The converter can start up from supply voltages as low as 0.7V, making it suitable for use with Li-Ion and other low voltage battery types.

The MAX1798EGP+T operates by converting a low-input voltage, typically between 0.7V to 4.5 V, into a regulated output voltage. This is done by providing a powerful and efficient buck-boost architecture. The device uses pulse-width modulation (PWM) to control the duty cycle of the inductor current. The duty cycle is held constant with constant frequency over input voltage and load current variances. The output voltage is maintained within a +-1.5% accuracy band to ensure stable operation in a wide range of conditions.

The MAX1798EGP+T also includes protection features to guard against both overloading and overvoltage situations. The device includes over-current protection, over-voltage protection, under-voltage lockout and thermal overload protection. This ensures reliable and safe operation of the device in harsh real-world environments.

The MAX1798EGP+T is an ideal solution for providing reliable and regulated step-up power and makes an excellent choice for applications such as portable computing, cameras, PDAs and media players. It is also suitable for any low-voltage input device that requires a regulated output voltage.
