Constant Maximum Switch Current Rating

at All Duty Cycles*

Available in a Small Thermally Enhanced

TSSOP-16 Package

The LT

3436 is an 800kHz monolithic boost switching

regulator. A high efficiency 3A, 0.1Ω switch is included on

the die together with all the control circuitry required to

complete a high frequency, current-mode switching regu-

lator. Current-mode control provides fast transient re-

sponse and excellent loop stability.

New design techniques achieve high efficiency at high

switching frequencies over a wide operating range. A low

dropout internal regulator maintains consistent perfor-

mance over a wide range of inputs from 24V systems to Li-

Ion batteries. An operating supply current of 1mA main-

tains high efficiency, especially at lower output currents.

Shutdown reduces quiescent current to 11µA. Maximum

switch current remains constant at all duty cycles. Syn-

chronization capability allows an external logic level signal

to increase the internal oscillator from 1MHz to 1.4MHz.

Full cycle-by-cycle switch current limit protection and ther-

mal shutdown are provided. High frequency operation al-

lows the reduction of input and output filtering components

and permits the use of tiny chip inductors. The LT3436 is

available in an exposed pad, 16-pin TSSOP package.
