GPM9082
Description
The GPM9082 step-up switching regulator generates an output voltage of up to 5.5V from an input voltage as low as 2.0V. Ideal for applications where space is limited, it switches at 1.0MHz, allowing the use of tiny, low cost and low profile external ponents. Its internal 2.5A, 100m Ω NMOS switch provides high efficiency even at heavy load, while the constant frequency, current mode architecture results in low, predictable output noise that is easy to filter. Internal frequency pensation is designed to acmodate ceramic output capacitors, further reducing noise. The device features very low shutdown current of 0.5u A. The GPM9082 features over current protection, open load protection, under voltage lock-out and over temperature protection. The GPM9082 is available in SOT-23-6 package.
