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, a minimum peak switch current rating of 3A, and a low resistance 0.1W power switch. The switch current limit is constant at all duty cycles. The small TSSOP 16-pin exposed leadframe package is optimal for high power in a tiny space with excellent heat dissipation capabilities. The small size and wide input voltage of the LT3436 are demonstrated by the 3.2V–12V input to 12V output boost converter. The maximum output current varies with respect to the input voltage as shown in Figure 2. The circuit is optimized for 5V input to 12V output. Compensation components are designed for stable operation over the entire input voltage range 3.2V–12V input for this 12V output application. Adjustable feedback resistors allow simple customization of the output voltage. Stability and transient response can be further optimized by choosing different compensation components for small input voltage ranges such as 5VIN ±10% or 3.6VIN to 5.4VIN. The high 800kHz switching frequency allows the use of tiny ceramic input and output capacitors as well as a very small inductor, making tiny and low cost boost converter solutions possible. High switching frequency results in lower output voltage ripple than lower frequency converters. Shutdown and synchronization terminals provide more options for battery-powered devices and systems with higher frequency requirements.
