TL1451ACD - CI Smd, SOIC16

TL1451ACD PWM Controller Circuit, 2 outputs, 3.6V-50V supply, 50V/10mA out, 500 kHz, SOIC-16

Descrição geral do produto
The TL1451ACD is a 2-channel Pulse Width Modulation (PWM) Controller with wide input voltage range. It incorporates on a single monolithic chip all the functions required in the construction of two pulse-width-modulation (PWM) control circuits. Designed primarily for power-supply control, the TL1451A contains an on-chip 2.5V regulator, two error amplifiers, an adjustable oscillator, two dead-time comparators, undervoltage lockout circuitry and dual common-emitter output transistor circuits. The uncommitted output transistors provide common-emitter output capability for each controller. The internal amplifiers exhibit a common-mode voltage range from 1.04 to 1.45V. The dead-time control (DTC) comparator has no offset unless externally altered and can provide 0 to 100% dead time. The on-chip oscillator can be operated by terminating RT and CT. During low VCC conditions, the undervoltage lockout control circuit feature locks the outputs off until the internal circuitry is operational.
