IC SMPS Controller KA7500C KA7500 IC Power Supply PSU SOP16

SMPS Controller IC KA7500C Form : 16-Lead SOP Feature : 1. Internal Regulator Provides a Stable 5V Reference Supply Trimmed to 1% Accuracy 2. Uncommitted Output TR for 200mA Sink or Source Current 3. Output Control for Push-Pull or Single-Ended Operation 4. Variable Duty Cycle by Dead-Time Control (Pin 4) Complete PWM Control Circuit 5. On-Chip Oscillator with Master or Slave Operation 6. Internal Circuit Prohibits Double Pulse at Either Output 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 (V REF ) is improved up to 1% with trimming. This provides a better output voltage regulation. The operating temperature range is -25C ~ +85C. Stok tersedia untuk diskusi produk silahkan kontak 08-222-802-5757
