Overview
The MIC2132 is a constant on-time, dual phase synchronous buck controller featuring a unique adaptive on-time control architecture with stackable feature up to eight phases. The MIC2132 operates over an input supply range from 8.0V to 75V and can be used to supply up to 50A of output current/phase. The output voltage is adjustable down to 0.6V with an ensured accuracy of ±1%. The device operates with programmable switching frequency from 100 kHz to 800 kHz per phase.
Features:
- Input voltage range: 8V to 75V
- Input down to 2V when VDD = 5V from external supply
- Adjustable output from 0.6V to 32V
- Adaptive Constant on Time Control
- High Delta V operation
- Any Capacitor™ Stable - 0.6V Internal reference with ±1% accuracy
- Operates in CCM, Stackable for Multiphase Operation up to Eight Phases
- Ripple injection from third node which allows greater than 50% duty cycles
- Accurate Current balancing between phases
- Accurate 180° phasing of outputs
- 100 KHZ to 800KHZ switching Frequency per phase
- High Voltage Internal 5V LDO for single supply operation
- Secondary LDO to improve system efficiency
- Supports start up to pre-bias output
- Remote sense amplifier for tight output regulation
- Supports Adaptive voltage positioning (AVP) or Droop
- Precision Enable function for low stand-by current
- External programmable soft start to reduce inrush current
- Programmable current limit and hiccup short circuit protection
