    Overview

    The Buck Experiments Board is one board as part of the Power Management Lab Kit (PMLK) Series. The Buck Experiments Board has two different sections using two different ICs: TPS54160 and LM3475. The box that is shipped will contain the Buck EVM Hardware along with a bound version of the Buck Experiments Book that steps individuals through several experiments to reinforce their understanding of power supply design. The PMLK is intended to educate users and developers on electronic theory and TI power supply design through experiments.

    The LM3475 is a hysteretic P-FET buck controller designed to support a wide range of high efficiency applications in a very small SOT-23-5 package. The hysteretic control scheme has several advantages, including simple system design with no external compensation, stable operation with a wide range of components, and extremely fast transient response. Hysteretic control also provides high efficiency operation, even at light loads. The PFET architecture allows for low component count as well as 100% duty cycle and ultra-low dropout operation.

    The TPS54160A device is a 60-V, 1.5-A, step down regulator with an integrated high-side MOSFET. Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load, regulated output supply current to 116 μA. Using the enable pin, shutdown supply current is reduced to 1.3 µA.
