General Description
The LM3478 is a versatile Low-Side N-Channel MOSFET controller for switching regulators.
It is suitable for use in topologies requiring a low side MOSFET, such as boost, flyback, SEPIC, etc.
Key Features
- such as thermal shutdown, short-circuit protection, over voltage protection, etc. Power saving shutdown mode reduces the total supply current to 5µA and allows power supply sequencing. Internal soft-start limits the inrush current at start-up. Key Specifications.
- Wide supply voltage range of 2.97V to 40V.
- 100kHz to 1MHz Adjustable clock frequency.
- ±2.5% (over temperature) internal reference.
- 10µA shutdown current (over temperature) Features.
- LM3478Q in MSOP-8 package is.
