|MIC28304 High Density Power Module - Micrel’s MIC28304 is a synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture. The module incorporates a DC-DC controller, power MOSFETs, input capacitor bootstrap diode, bootstrap capacitor, and an inductor in a single package. The MIC28304 operates over an input supply range from 4.5 V to 70 V and can supply up to 3 A of output current. The output voltage is adjustable down to 0.8 V with a guaranteed accuracy of ±1%. The device operates with programmable switching frequency from 200 kHz to 600 kHz.
|MIC45205/45208/45212 Power Modules - Micrel’s MIC45205/08/12 is a family of 6 A/10 A/14 A highly efficient DC/DC power modules. These modules are specifically designed to deliver extremely-high performance at lower output voltages, as required by future high-speed digital processor cores.
|MIC4605 Half Bridge MOSFET Drivers - The Micrel MIC4605 is an 85 V Half-Bridge MOSFET driver that features Adaptive-Dead-Time and Shoot-Through protection. The Adaptive-Dead-Time circuitry actively monitors the Half Bridge to minimize the time between high- and low-side MOSFET transitions, which maximize power efficiency. Anti-Shoot-Through circuitry prevents erroneous inputs and noise from turning both MOSFETs on at the same time. The MIC4605 also offers a wide 5.5 V to 16 V operating supply range to maximize system efficiency. The low 5.5 V operating voltage allows longer run times in battery-powered applications.
|MIC4604 MOSFET Drivers - The Micrel MIC4604 is an 85 V half-bridge MOSFET driver. The MIC4604 features fast 39 ns propagation delay times and 20 ns driver rise/fall times for a 1 nF capacitive load. The low- and high-side gate drivers are independently controlled. The MIC4604 has TTL input thresholds. It includes a high-voltage internal diode that helps charge the high-side gate drive bootstrap capacitor. A robust, high-speed, and low-power level shifter provides clean level transitions to the high-side output.
