Data Sheet PULSE-WIDTH-MODULATION CONTROL CIRCUITS General Description Features AZ7500B/C The AZ7500B/C is a voltage mode pulse width modu- - Stable 4.95V/5V Reference Voltage Trimmed to lation switching regulator control circuit designed pri- ±1.0% Accuracy marily for power supply control. - Unmitted Output TR for 200m A Sink or Source Current The AZ7500B/C 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 AZ7500B/C 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 AZ7500B/C is available in standard packages of DIP-16 and SOIC-16.
