Data Sheet PULSE-WIDTH-MODULATION CONTROL CIRCUITS General Description Features The AZ7500C is a voltage mode pulse width modula- - Stable 5V Reference Voltage Trimmed to ±1.0% tion switching regulator control circuit designed pri- Accuracy marily for power supply control. - Unmitted Output TR for 200m A Sink or Source Current The AZ7500C consists of a reference voltage circuit, - Single-End or Push-Pull Operation Selected by two error amplifiers, an on-chip adjustable oscillator, a Output Control dead-time control (DTC) parator, a pulse-steering - Internal Circuitry Prohibits Double Pulse at Either control flip-flop, and an output control circuit. The precision of voltage reference (VREF) is improved up to ± - Output plete PWM Control Circuit with Variable 1% through trimming and this provides a better output Duty Cycle voltage regulation. The AZ7500C provides for push- - On-Chip Oscillator with Master or Slave Opera- pull or single-ended output operation, which can be tion selected through the output control. The difference between AZ7500B and AZ7500C is that they have 4.95V and 5V reference voltage respectively. The AZ7500C is available in standard package of SOIC-16.
