DC-DC Controllers Product Line for Consumer, Industrial & Telecom Applications
Akros Silicon Launches DC-DC Controllers with Gate Drive Signal Shaping to Reduce EMI and Increase Efficiency
The AS12xx series is configurable for flyback, forward, boost or buck power topologies used in both isolated and non-isolated converter designs. Capable of providing up to 100W, the AS12xx devices’ current-mode architecture provides a fast-loop response and very low “no load” power consumption.
Wide input voltage range of 8.5V to 57V and high single-rail output current enable AS12xx devices to be used in a wide variety of consumer electronic equipment such as set-top boxes, LCD televisions, DVRs, printers, indoor WiFi access points as well as in industrial Ethernet, motor control applications, automotive power and telematics sub-systems.
AS1228, AS1230, AS1257 and AS1260 devices integrate Electrostatic Discharge (ESD) and thermal protection, 100kHz to 500kHz programmable Pulse-Width Modulation (PWM) operation and programmable soft-start. FET gate drive signals are shaped to minimize switching noise and improve Electromagnetic Interference (EMI) performance.
The AS12xx family provides superior gate driver output resistance and rise/fall times, further optimizing system performance to deliver > 92% efficiency.
