diodes inc (DDQ) Key Developments

Diodes Incorporated Introduces Dual-Phase Synchronous Rectified Buck Controller

Diodes Incorporated introduced a dual-phase synchronous rectified buck controller, optimized for use in high-performance GPU and CPU core power supplies. Providing PWM video-identification dynamic-output voltage control, the AP3598A assures the fast, high-current response demanded by the inherently large variations in output loading. The device includes a PWM controller, a pair of MOSFET drivers with internal bootstrap diodes, channel-current balance and comprehensive protection features integrated into the compact, low pin-count U-QFN4040-24 package. Designed for 12V systems, it delivers an output current as high as 60A and harnesses external compensation to minimize output voltage ripple and optimize transient response. Accurate phase current balance is maintained through lossless RDS(ON) current sensing, while inductor current sampling ensures a dependable current limit. To help maximize efficiency, the AP3598A offers a power-save mode, which enables it to switch automatically between dual- and single-phase operation when subject to light loading. For safe high-current operation, the controller provides a full complement of protection functions including over-current, over-temperature, and under- and over-voltage protection. Other features include adjustable soft-start, adjustable operating frequency selection, and a power-good indicator and enable control.

Diodes Incorporated Introduces PAM2401

Diodes Incorporated introduced the PAM2401. This device is a low voltage 1MHz step-up DC-DC converter designed to meet the heightened efficiency demands of portable products including battery backups, cordless phones and GPS receivers. Maintaining 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 input operation voltage range of 0.9V to 4.75V. To help maximize battery life, the device automatically enters a high-efficiency pulse-skipping mode when driving light loads.

Diodes Incorporated Introduces the AP22802

Diodes Incorporated introduced the AP22802. This single-channel load switch ensures extensive protection for interconnects that are subject to the risk of surges and short circuits. The AP22802 quickly clamps output current to a safe level upon fault sensing. This highly integrated device is optimized for regular USB and other hot-swap applications and is available in the small form-factor SOT25 package, offering a footprint of only 9mm. The AP22802 sets a typical current limit of 2.7A to guard against overloads and operates over an input voltage range of 2.7V to 5.5V. For added flexibility, this load switch offers circuit designers the choice of either active-low and active-high enable inputs. The device's under-voltage lockout function ensures that the internal power switch remains off until input power level has reached a minimum of 2V, even if the switch is enabled, which is useful for the design of single-channel, hot-insert systems.
