₨ 25
-
🌈 Complete PWM Circuitry: All functions for pulse-width modulation control are integrated on a single monolithic chip.
-
🔄 Dual Output Modes: Supports both Single-Ended and Push-Pull operations, selectable via the output-control pin.
-
🛡️ Dead-Time Control (DTC): Built-in adjustable dead-time provides a safe buffer to prevent power transistor overlap and damage.
-
🧠 On-Chip Error Amplifiers: Includes two high-gain error amplifiers with a common-mode voltage range of $-0.3V$ to $V_{CC}-2V$.
-
⏱️ Adjustable Oscillator: Features a programmable internal oscillator with frequency control via external $R$ and $C$ components.
-
🛑 Double-Pulse Prevention: Internal flip-flop logic prevents double pulsing at the outputs during push-pull operation.
-
🔗 Easy Synchronization: The architecture allows for simple synchronization with other ICs for multi-rail power systems.
-
⚙️ Uncommitted Outputs: Dual output transistors can sink or source up to 200mA each, offering flexible drive options.
