TL494CDR SMD IC Texas Instruments SOIC16 TL494CDR

Product Overview: A surface-mount, pulse-width-modulation (PWM) control integrated circuit designed to incorporate all the primary functions required to construct a PWM control circuit on a single chip. Primarily engineered for power supply control, it offers the flexibility to tailor power-control circuitry to specific applications.

Core Specifications:

Manufacturer: Texas Instruments

Package Type: Available in various 16-pin packages including SOIC (D), SSOP (DB), PDIP (N), SOP (NS), and TSSOP (PW)

Function: Pulse-Width-Modulation (PWM) Control Circuit

Input Channels: N/A (Power Management/Control IC)

Control Interface: Hardware Pin-Controlled (Single-Ended or Push-Pull Output Control Selection)

Features:

• Complete PWM power control circuitry on a single monolithic chip

• Uncommitted outputs providing up to 200 mA sink or source current capability

• Output control feature allowing selection between single-ended or push-pull operation modes

• Internal circuitry designed to prohibit double pulses at either output

• Variable dead-time control across the entire operational range

• Internal regulator providing a stable 5-V reference supply with 5% tolerance

• Circuit architecture designed to allow easy synchronization with external circuits

Applications:

• Desktop computers and server power supply units (PSU)

• Microwave ovens and consumer appliances

• Isolated AC/DC power supplies with or without Power Factor Correction (PFC)

• Photovoltaic microinverters and solar inverters

• Electric bicycles and e-mobility systems

• Smoke detectors and safety instrumentation systems
