Announcement: Check out our latest video on the HL5301, the industry's smallest SIM card level translator.

Overview

The HL7507 is a synchronous buck converter optimized to supply different sub systems of portable applications. Its input voltage range is 2.5-5.5V. Its output voltage is a factory pre-set value and 2 optional output ranges are available for various application fields.

The HL7507 can deliver up to 1.5A while maintaining over 80% efficiency at load currents as low as 10mA. It operates at a high frequency of 3MHz, which greatly reduces the value of the external components. A wide range of output capacitors can be used to optimize VOUT stability during load transients. The inductors from 0.33μH to 1.0μH may be used without affecting loop stability.
