TL5002 is a pulse-width-modulation control circuit launched by Texas Instruments. It is suitable for applications in the voltage range of 3.6V-40V, and has an internal undervoltage lockout circuit. It can provide a 20kHz to 500kHz oscillation frequency and support 0-100% dead time control. It is ideal for DDR memory applications and has uncommitted error amplifier inputs
The TL5002 is a monolithic chip designed primarily for power-supply control, incorporating an error amplifier, regulator, oscillator, PWM comparator with dead-time control, undervoltage lockout, and an open-collector output transistor. It is characterized for operation from -40°C to 85°C and is ideal for DDR memory applications.
Key features include a 2.5-V internal voltage reference, an uncommitted error amplifier with a 15 MHz unity-gain bandwidth, and an oscillator frequency adjustable between 20 kHz and 500 kHz. The device includes a dead-time control input to limit duty cycle and an undervoltage-lockout circuit to protect against low supply voltages.
