The LMC555 device is a CMOS version of the industry standard 555 series general-purpose timers. In addition to the standard SOIC, VSSSOP, and PDIP packages, the LMC555 is also available in a chip-sized, 8-bump DSBGA package using TI’s DSBGA package technology. The LMC555 offers the same capability of generating accurate time delays and frequencies as the LM555, but with much lower power dissipation and supply current spikes. When operated as a one-shot, the time delay is precisely controlled by a single external resistor and capacitor. In astable mode, the oscillation frequency and duty cycle are accurately set by two external resistors and one capacitor. TI’s LMCMOS process extends both the frequency range and the low supply capability.

LMG5200POLEVM-10 — LMG5200 GaN 48V to 1V point of load evaluation module

The LMG5200POLEVM-10 EVM is designed to evaluate the LMG5200 GaN power stage and the TPS53632G half-bridge point-of-load controller in a 48V to 1V application.  This EVM implements the 48V-1V converter as a single-stage hard-switched half-bridge with current-doubler rectifier.  The EVM (...)
