Analog Devices has introduced the LTM4668 and LTM4668A µModule quad-output DC/DC regulators with up to 4.8A output capability. The new devices integrate switching controllers, power FETs, inductors and support components, easing the design process while reducing power consumption and board space: this makes them ideal for telecommunications, networking and industrial applications.
Operating over an input voltage range of 2.7V to 17V, the LTM4668 and LTM4668A support an output voltage range of 0.6V to 5.5V. The devices support frequency synchronisation, PolyPhase operation, selectable Burst Mode operation, 100 per cent duty cycle and low IQ operation. Their high switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
