OM73331 is a 4A, step-up converter with an input voltage range of 3.5V - 30V. The fixed switching frequency is 1.1MHz and the built-in compensation device can effectively reduce the size and number of external components, making it suitable for size-constrained electronic devices such as cameras and mobile phones.
The device has a built-in soft-start function to prevent possible overshoot voltage and surge current. Cycle-by-cycle current limiting, input undervoltage lockout and thermal shutdown ensure stable operation of the device.
The OM73331 uses QFN4*4-16L and DFN3*3-10L packages with a rated junction temperature range of -40°C to 125°C.
