4MHz Step-down Converter Description smallest solution size power conversion.
AE2359 The AE2359 is a current mode step-down converter with a built-in power MOSFET to enable With the low series resistance power switch it enables a constant output current of up to 1.
2A over a wide input supply range.
The load and line regulation has excellent response time over the operating input voltage and temperature range.
The AE2359 is self protected, through a cycle-by-cycle current limiting algorithm and an on chip thermal protection.
The AE2359 will provide the voltage conversion with a low count of widely available standard external components.

4MHz Step-down Converter Pin Assignments AE2359 PIN DESCRIPTION Pin 1 Name BST Description Bootstrap.
To form a boost circuit, a capacitor is connected between SW and BST pins to form a floating supply across the power switch driver.
This capacitor is needed to drive the power switch’s gate above the supply voltage.
Typical values for CBST range from 0.
1uF to 1uF.
Ground.
This pin is the voltage reference for the regulated output voltage.
All control circuits are referenced to this pin.
For this reason care must be taken in its layout.
Feedback.
To set the output voltage, connect this pin to the output resistor divider or directly to VOUT.
To prevent current limit run away during a current limit condition, the ...
