LP3219
1.5MHz, 2A Step-Down Converter
概述
The LP6461 is a synchronous buck converter supporting up to 3A output current. The LP6461 operates over a wide input voltage range from 4.5V to 16V and integrates main switch and synchronous switch with very low RDS(ON) to achieve high efficiency. The LP6461 integrates two operation modes, PWM control and PFM mode switching control, which allows a high efficiency over the wider range of the load. Other features include over current protection(OCP), over temperature protection(OTP), under-voltage lockout(UVLO)and short circuit protection(SCP).The LP6461 is available in a space saving SOT23-6 package.
