KA7500B Step Down DC-DC Controller IC DIP-16

Description

Description The KA7500B is u sed for the control circuit of the PWM switching regulator. The KA7500B consists of 5V reference voltage circuit, two error amplifiers, a 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. Features Internal Regulator Provides a Stable SV Reference Supply Trimmed to 5% 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 Product Attributes TYPE DESCRIPTION Category Integrated Circuits (ICs) Power Management (PMIC) DC DC Switching Controllers Output Type Transistor Driver Function Step-Down Output Configuration Positive Topology Buck Number of Outputs 1 Output Phases 1 Voltage – Supply (Vcc/Vdd) 7V ~ 42V Frequency – Switching 1kHz ~ 300kHz Duty Cycle (Max) 45% Synchronous Rectifier Yes Clock Sync No Control Features Dead Time Control Operating Temperature 0°C ~ 70°C (TA) Mounting Type Through Hole Package / Case 16-DIP Base Product Number KA7500 Applications: DC-DC Buck Converters: Converts a higher DC input voltage to a lower DC output voltage.
