1A DC-DC Buck Converters from Diodes Incorporated Achieve High Efficiency Under Light-Load and Full-Load Conditions

PLANO, Texas — (BUSINESS WIRE) — August 9, 2016 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today announced the AP3401 and AP3428. These DC-DC step-down converters are capable of driving loads up to 1A with excellent line- and load-regulation provided by a constant-frequency PWM control that requires no external compensation and so minimizes component count and material costs. Developed to meet the demands of set-top boxes, TVs, routers, Wi-Fi modules and security systems, these buck converters feature low power consumption and highly-efficient light-load operation.

The AP3401/3428 operate from an input voltage between 2.5V and 5.5V, making them well-suited for use with a single Li+/Li-polymer cell, multiple Alkaline/NiMH cells and other power sources; they also deliver an output voltage from 0.6V up to the full input voltage with an output current up to 1A. The high-current and low-dropout threshold performance is achieved with the benefit of integrated ultra-low RDS(ON) MOSFETs and the ability to operate at 100% duty cycle with a switching frequency up to 1.5MHz. The AP3401 also features a power-good output.

An integrated soft-start reduces start-up current spikes to avoid system damage when switching power on or off. Other features for protection of the IC and system include over-current, under-voltage lockout and over-temperature with thermal shutdown. The AP3401/3428’s DFN2020 package with exposed pads provides the power handling capability needed for thermally demanding consumer applications.
