Rating & Review

Texas Instruments UC3526AN is a high-performance voltage-mode PWM controller in an 18-pin PDIP (through-hole) package. Designed for robust DC-DC converter applications, it supports a range of flexible topologies, including buck, boost, flyback, forward, full-bridge, half-bridge, and push-pull, making it an ideal foundation for versatile power supply designs.

Unique Features of the Product

Maximum Switching Frequency: Up to 600 kHz
Output Current (per output): 0.2 A (200 mA) using dual source/sink outputs
Duty Cycle (Max): Approx. 49–50 %
Working Temperature: 0 °C to +70 °C (TA)
Package Type: PDIP‑18 (through‑hole)
Rise/Fall Times: ~300 ns (rise), ~100 ns (fall)

Unparalleled Benefits to Customers

Enhanced Performance: Reduced supply current and improved oscillator stability for reliable, noise‑resilient operation.
Advanced Protection: Built-in under-voltage lock-out, programmable soft-start, thermal shutdown, and double-pulse suppression ensure safe startup and fault tolerance.
Logic Compatibility & Sync: TTL/CMOS logic‑compatible control pins (enable, reset, frequency control), plus a synchronisation input for multi‑phase or coordinated systems.
Precision Reference: A stable band‑gap voltage reference enhances regulation accuracy across variable load and supply conditions.
Topology Flexibility: Suitable for a wide array of converter types, providing design versatility for power electronics engineering.

Applicable Areas

Ideal for industrial and power-electronics systems demanding compact, reliable PWM control, such as SMPS, embedded power modules, and control systems where through-hole mounting and robust protection are desired.
