K78 series with 0.5A / 1A / 2A output received the warm response from the market since its launch because of excellent performance, high reliability, and attractive cost. To better fulfill the demand for higher current output, we are pleased to extend the K78_3AR3 with 3A output current.
K78-3AR3 features ultra-wide input voltage range of 8-36V, 2mA no-load input current, 97% efficiency and -40 ℃ to + 85 ℃ operating temperature range without heat sink. At the same time, K78_3AR3 series has the characteristics of continuous short-circuit protection, low ripple noise (typical value 40mV) and so on. Different package of encapsulated SIP and open-frame SIP are available.
It can be used on non-isolated step-down circuit (it means that the input voltage is higher than the output voltage), universal product, and any industry.
● High efficiency up to 97%
● No-load input current as low as 2mA
● Operatin temperature range: -40℃ to +85℃
● Input voltage range: 8-36V
● Output short-circuit protection
