1 / 8 page April 2009 © 2003 Fairchild Semiconductor Corporation www.fairchildsemi.com KA7500C • Rev. 1.0.2 KA7500C SMPS Controller Features Internal Regulator Provides a Stable 5V Reference Supply Trimmed to ±1% Accuracy Uncommitted Output TR for 200mA Sink or Source Current Output Control for Push-Pull or Single-Ended Operation Variable Duty Cycle by Dead-Time Control (Pin 4) Complete PWM Control Circuit On-Chip Oscillator with Master or Slave Operation Internal Circuit Prohibits Double Pulse at Either Output Description The KA7500C is used for the control circuit of the pulse- width 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 Eco Status Package Packing Method KA7500C 16-Lead Dual Inline Package (DIP) Tube KA7500CD Tube KA7500CDTF -25 to +85°C RoHS 16-Lead Small Outline Package (SOP) Tape and Reel For Fairchild’s definition of Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html. |
