EMH7090-00SG08NRR
The EMH7090 is a monolithic asynchronous boost DC-DC converter. Its PWM circuitry with built-in 6A 60mΩ power MOSFET make this regulator highly power efficient.
The EMH7090 has wide input voltage range from 2.9V~12V to support applications with single-cell or two-cell lithium batteries. The device could have 6A switching current capacity to provide an output voltage up to 14V.
The EMH7090 uses current mode PWM control topology to regulate the output voltage. That works into power saving mode to get better efficiency for battery in light load condition. In heavy load condition, the EMH7090 works into PWM operating mode.
The EMH7090 non-inverting input of error amplifier connects to 0.6V precision reference voltage and internal soft-start function can reduce the inrush current. In addition, overvoltage protection, cycle by cycle over current protection, and thermal shutdown protection are designed into this chip.
The EMH7090 is available in E-SOP-8L package and provides space-saving PCB for the application fields.
