Qty.Volume Price

A 200KHz switching frequency, combined with a synchronous rectifier buck regulator topology, provides for efficiencies exceeding 95% while easily driving 2A loads from 12V or 24V supplies, all at ambient temperatures up to +70°C without heat sinks, fans, or thermal derating. A thermally efficient 3-pin vertical mount SIP occupies less than 0.09in. ^2 (58mm2) of pc-board real estate, while a horizontal mount option has an installed height of less than 0.290in. (7.4mm)
