Data Sheets:
The MIC33153 is a high-efficiency 4MHz 1.2A synchronous buck regulator with an internal inductor, HyperLight Load® mode, Power Good (PG) output indicator, and programmable soft start. HyperLight Load® provides very high efficiency at light loads and ultra-fast transient response which makes the MIC33153 perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors.
The MIC33153 is designed so that only two external capacitors as small as 2.2 µF are needed for stability. This gives the MIC33153 the ease of use of an LDO with the efficiency of a HyperLight Load® DC converter. The MIC33153 achieves efficiency in HyperLight Load® mode as high as 85% at 1mA, with a very low quiescent current of 22µA. At higher loads, the MIC33153 provides a constant switching frequency up to 4MHz.
The MIC33153 is available in 14-pin 3.0mm x 3.5mm package with an operating junction temperature range from -40°C to +125°C.
- Simplifies design to two external capacitors
- Input voltage: 2.7V to 5.5V
- Output voltage: fixed or adjustable (0.62V to 3.6V)
- Up to 1.2A output current
- Up to 93% peak efficiency
- 85% typical efficiency at 1mA
- Power Good (PG) output
- Programmable soft start
- 22µA typical quiescent current
- 4MHz PWM operation in continuous mode
- Ultra-fast transient response
- 35mVpp ripple in HyperLight Load® mode
- 7mV output voltage ripple in full PWM mode
- 0.01µA shutdown current
- Thermal shutdown
