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.
The ICs implement a 500kHz (MIC2155) and 300kHz (MIC2156) voltage mode PWM control, with the outputs switching 180° out of phase.
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 n.
