The MAX1960/MAX1961/MAX1962 high-current, highefficiency voltage-mode step-down DC-DC controllers operate from a 2.
Features
* o 0.5% Accurate Output o Operates from 2.35V to 5.5V Supply o Generates Low Output Voltage Down to 0.8V o o o o o o o o On-Chip Charge Pump Provides 5V Gate Drive Ceramic or Electrolytic Capacitors 94% Efficiency External Synchronization from 450kHz to 1.2MHz 500kHz/1MHz Fixed-Frequency PWM Operatio
Applications
* The operating frequency is programmable to either 500kHz or 1MHz, or from 450kHz to 1.2MHz with an external clock. A clock output is provided to synchronize another converter for 180° out-of-phase operation. A high closed-loop bandwidth provides excellent transient response for applications with dy
