LT3493
1.2A, 750kHz Step-Down
Switching Regulator in
2mm × 3mm DFN
FEATURES DESCRIPTION n The LT®3493 is a current mode PWM step-down DC/DC
converter with an internal 1.75A power switch. The wide
operating input range of 3.6V to 36V (40V maximum)
makes the LT3493 ideal for regulating power from a wide
variety of sources, including unregulated wall transformers, 24V industrial supplies and automotive batteries.
Its high operating frequency allows the use of tiny, low
cost inductors and ceramic capacitors, resulting in low,
predictable output ripple. Wide Input Range: 3.6V to 36V Operating,
40V Maximum
