Micrel – MIC23450/51: Triple Output Synchronous Buck Regulators with HyperLight Load
The MIC23450 and MIC23451 are two triple-output, high-efficiency synchronous buck regulators designed with Micrel’s HyperLight Load technology. The MIC23450 delivers two amps per output and the MIC23451 provides one amp per output. Both regulators operate at 3MHz in PWM mode, which allows the use of tiny, low-cost capacitors and inductors thereby creating one of the smallest, simplest to use triple-buck regulators in the industry.
Design engineers may program each of the three outputs independently to operate from 1.0V to 3.3V using external resistors. The MIC23450/51 support an input voltage range of 2.7V to 5.5V making them both ideal for Li-ion/polymer or alkaline/NiCad/NiMH applications, as well as point-of-load (POL) DC-to-DC conversions; an area where maximizing power density and efficiency is paramount.<
The MIC23450 is offered in a thermally-enhanced 32-pin 5mm x 5mm thin MLF(R) package and the MIC23451 is offered in small 26-pin 4mm x 4mm MLF option. The MIC23450/51 offer very low quiescent current (23uA/channel) and achieve as high as 81 percent efficiency at load current as low as 1mA with peak efficiency over 93 percent. In addition, the ICs offer three Power Good (PG) output indicators and enable inputs for power sequencing. The solutions all operate at -40oC to +125oC junction temperature range.

MIC2405x: Family of Integrated FET DC-DC Buck Converters from Micrel
The MIC2405x family is Micrel’s latest-generation SuperSwitcher IITM family of integrated MOSFET buck regulators optimized for the 12V rails, with 6A/9A/12A output supply current. The MIC2405x family comprises of six common-footprint, DC-to-DC buck regulators that leverage Micrel’s proprietary HyperSpeed ControlTM and HyperLight Load(R) architectures.
The MIC2405x family of devices operates with a single-input supply voltage range from 4.5V to 19V, and delivers output currents of 6A, 9A and 12A respectively, all in small footprint MLF-28, 5mmx 6mm packages. The common footprint shared by all devices in this family enables current scalability to provide design flexibility for power supplies. This family of regulators has been tailored to be Any CapacitorTM stable, independent of the output capacitance Equivalent Series Resistance (ESR), thus solving the perpetual problem of stability that power designers face when dealing with distributed output capacitance. Moreover, these buck regulators provide more than 95 percent peak efficiency and operate at 600kHz switching frequency with ±1 percent of output voltage accuracy (with output adjustable down to 0.8V).
- Versatile Buck Regulators
- Small Solution Size and Cost
- Low Power Consumption
- Fully Protected
- Flexible Packaging
The MIC2405x regulators offer a full suite of protection features to ensure protection of the IC during fault conditions.
