Description

The TL594CD is a Pulse Width Modulation (PWM) Controller on a single chip. Designed primarily for power-supply control, this device offers the systems engineer the flexibility to tailor the power-supply control circuitry to a specific application. The TL594 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5V regulator with a precision of 1%, an undervoltage lockout control circuit and output control circuitry. The error amplifiers have a common-mode voltage range of -0.3V to VCC - 2V. The DTC comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating RT to the reference output and providing a sawtooth input to CT, or it can be used to drive the common circuitry in synchronous multiple-rail power supplies. The uncommitted output transistors provide either common-emitter or emitter-follower output capability.
Uncommitted outputs for 200mA Sink or source current
Output control selects single-ended or push-pull operation
Internal circuitry prohibits double pulse at either output
Variable dead time provides control over
Reference supply trimmed to 1%
Circuit architecture allows easy synchronization
Undervoltage lockout for low VCC conditions
Green product and no Sb/Br
