QFN Package
n 24-Lead Exposed Pad TSSOP The LT®3514 consists of three buck regulators (2A, 1A,
1A output current). The device has a wide operating input
range of 3.2V to 36V. An on-chip boost regulator allows
each channel to operate up to 100% duty cycle. The LT3514
is designed to minimize external component count and
results in a simple and small application circuit. APPLICATIONS The LT3514 has one fewer channel (CH2) than the LT3504,
and has one channel (CH3) that outputs 2A instead of 1A. …
