Functional Description
low-noise PWM topology. Up to 6A of continuous
output current can be drawn from this converter.
The 4MHz operating frequency enables the use
of small-size input and output capacitors.
Synchronous Buck Converter
The EN5364QI is a synchronous, programmable
power supply with integrated power MOSFET
switches and integrated inductor. The nominal
input voltage range is 2.375-6.6V. The output
voltage is programmed using an external resistor
divider network. The feedback control loop is a
type III, voltage-mode, and the device uses a
The power supply has the following protection
features:
• Over-current protection with hiccup mode.
• Short Circuit protection.
