Diodes Inc. PAM2401 DC to DC Converters

Diodes Inc. PAM2401
Step-Up DC to DC Converters

Diodes Inc. PAM2401 DC to DC Converters are low voltage 1MHz step-up DC-DC converters designed to meet the heightened efficiency requirements of portable devices including battery backups, cordless phones, and GPS receivers. With an operational efficiency as high as 95%, this synchronous converter provides true output disconnect to prevent leakage and ensures safe start-up at an input as low as 1V. The PAM2401 offers a programmable current limit of 1.0A to 3.0A for its lower operating voltage input range of 0.9V to 4.75V. To help maximize battery life, PAM2401 automatically enters a high-efficiency pulse-skipping mode when driving light loads. In shutdown, quiescent current is less than 1µA. By operating at a high fixed-switching frequency and integrating an N-channel MOSFET switch, a P-channel synchronous rectifier and a power-good indicator into MSOP-8 and U-DFN3030-12 packages, the PAM2401 reduces the number and size of external components and overall board space requirement. The converter also provides over-voltage and over-temperature protection functions, with the device's soft-start circuit ensuring safe automatic restart. Other features include anti-ringing control and hiccup-mode short-circuit protection.
