Additional Details

The LT3436 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 regulator. Current-mode control provides fast transient response 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 performance over a wide range of inputs from 24V systems to Li- Ion batteries. An operating supply current of 1mA maintains high efficiency, especially at lower output currents. Shutdown reduces quiescent current to 11µA. Maximum switch current remains constant at all duty cycles. Synchronization 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 thermal shutdown are provided. High frequency operation allows 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.

Product Detail

Demonstration circuit 533 is an 800kHz adjustable output boost regulator featuring the LT3436. This current-mode control monolithic (switch included) converter has a wide operating supply voltage of 3V to 25V and a minimum peak switch current rating of 3A, though the demo board has a reduced input voltage range of 3.2V to 12V. It provides 12V at 550mA from a 3.3V input and 12V at 900mA from a 5V input.
