MIC2155
Description
The MIC2155 and MIC2156 are a family of two-phase, single-output synchronous buck control ICs featuring small size, high efficiency, and a high level of flexibility.
Key Features
- Synchronous buck control ICs with outputs switching 180° out-of-phase
- Remote sensing with internal differential amplifier
- 4.5V to 14.5V input voltage range
- Adjustable output voltages down to 0.7V
- 1% output voltage accuracy
- Starts up into a pre-biased output
- 500kHz PWM operation (MIC2155)
- 300kHz PWM operation (MIC2156)
- Adaptive gate drive allows efficiencies over 95%
- Adjustable current limit with no sense resistor
