1 / 12 page  PULSE-WIDTH-MODULATION CONTROL CIRCUITS AZ7500C Data Sheet 1 May 2010 Rev. 1. 8 BCD Semiconductor Manufacturing Limited General Description The AZ7500C is a voltage mode pulse width modula- tion switching regulator control circuit designed pri- marily for power supply control. The AZ7500C consists of a reference voltage circuit, two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, and an output control circuit. The pre- cision of voltage reference (VREF) is improved up to ± 1% through trimming and this provides a better output voltage regulation. The AZ7500C provides for push- pull or single-ended output operation, which can be 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. Features · Stable 5V Reference Voltage Trimmed to ±1.0% Accuracy · Uncommitted Output TR for 200mA Sink or Source Current · Single-End or Push-Pull Operation Selected by Output Control · Internal Circuitry Prohibits Double Pulse at Either Output · Complete PWM Control Circuit with Variable Duty Cycle · On-Chip Oscillator with Master or Slave Opera- tion Applications · SMPS · Back Light Inverter · Charger Figure 1.
