Introduction
Microchip’s MIC28304 is a synchronous, step-down regulator module, featuring a unique adaptive on-time control architecture. The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor and an inductor in a single package. The MIC28304 operates over an input supply range from 4.5V to 70V and can be used to supply up to 3A of output current. The output voltage is adjustable down to 0.8V with an ensured accuracy of ±1%. The device operates with a programmable switching frequency from 200 kHz to 600 kHz.
Microchip’s HyperLight Load architecture provides the same high-efficiency and ultra-fast transient response as the Hyper Speed Control architecture under the medium to heavy loads. The architecture also maintains high efficiency under light load conditions by transitioning to Variable Frequency Discontinuous mode operation.
The MIC28304 offers a full suite of protection features. These include undervoltage lockout, internal soft start, foldback current limit, “Hiccup” mode short-circuit protection and thermal shutdown.
Features
- Easy to Use: Stable with low-ESR ceramic output capacitor - No compensation and no inductor to choose
- 4.5V to 70V Input Voltage
- Single-Supply Operation
- Power Good (PG) Output
- Low Radiated Emission (EMI) per EN55022, Class B
- Adjustable Current Limit
- Adjustable Output Voltage from 0.8V to 24V (also limited by duty cycle)
- 200 kHz to 600 kHz Programmable Switching Frequency
- Supports Safe Start-up into a Pre-Biased Output
- -40℃ to +125℃ Junction Temperature Range
- Available in 64-Pin, 12 mmx12 mmx3 mm QFN Package
Applications
- Distributed Power Systems
- Industrial, Medical, Telecom and Automotive
