XR3403D
DESCRIPTION
The XR3403D is a high frequency, high efficiency DC to DC converter with an integrated 4A, 0.1Ω power switch capable of providing an output voltage up to 14V. The fixed 1.2MHz allows the use of small external inductions and capacitors and provides fast transient response. It integrates Soft start, p,. only need few ponents outside.
It can be adjusted SW current limit by one resistor or one analog voltage.
