Product Introduction
The 4 MHz 1.2A synchronous buck regulator has an internal inductor, HyperLight Load® mode, Power Good (PG) output indicator, and programmable soft-start. HyperLight Load® provides high efficiency at light loads and ultra-fast transient response, suitable for supplying processor core voltages. It has very low output ripple voltage throughout the entire load range with small output capacitors.
Only two external capacitors as small as 2.2 μF are needed for stability, combining the ease of use of an LDO with the efficiency of a HyperLight Load® DC converter. It achieves up to 85% efficiency at 1 mA in HyperLight Load® mode with a 22 μA quiescent current. At higher loads, it provides a constant switching frequency up to 4 MHz.
It is available in a 14-pin 3.0 mm × 3.5 mm TDFN package with an operating junction temperature range from -40°C to +125°C.
