SMPS Controller

KA7500C — SMPS Controller April 2009 KA7500C SMPS Controller Features ƒ Internal Regulator Provides a Stable 5V Reference Supply Trimmed to ±1% Accuracy ƒ Uncommitted Output TR for 200mA Sink or Source Current ƒ Output Control for Push-Pull or Single-Ended Operation ƒ Variable Duty Cycle by Dead-Time Control (Pin 4) Complete PWM Control Circuit ƒ On-Chip Oscillator with Master or Slave Operation ƒ Internal Circuit Prohibits Double Pulse at Either Output Description The KA7500C is used for the control circuit of the pulsewidth modulation switching regulator. The KA7500C consists of 5V reference voltage circuit, two error amplifiers, flip flop, an output control circuit, a PWM comparator, a dead-time comparator, and an oscillator. This device can be operated in the switching frequency of 1kHz to 300kHz. The precision of voltage reference (VREF) is improved up to ±1% with trimming. This provides a better output voltage regulation. The operating temperature range is -25°C ~ +85°C. 16-Lead DIP 16-Lead SOP Ordering Information Part Number Operating Temperature Range KA7500C KA7500CD KA7500CDTF -25 to +85°C Eco Status RoHS Package Packing Method 16-Lead Dual Inline Package (DIP) 16-Lead Small Outline Package (SOP) Tube Tube Tape and Reel For Fairchild’s definition of Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html. © 2003 Fairchild Semiconductor Corporation KA7500C • Rev. 1.0.2 www.fairchildsemi.com KA7500C — SMPS Controller B.
