HM3420B - N-Channel Enhancement Mode Power MOSFET
The HM3420B is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture.
The device is available in an adjustable version.
Supply current with no load is 40uA and drops to <1uA in shutdown.
The 2.5V to 5.5V input voltage range makes the HM3420B id
