Silicon General/Microsemi - SG3526J - IC. PWM, Pulse Width Modulator.
Silicon General/Microsemi - SG3526J - IC. PWM, Pulse Width Modulator.
Status: Discontinued
The is a high performance monolithic pulse width modulator circuit designed for fixed-frequency switching regulators and other power control applications. Included an 18-pin dual-in-line package are a temperature compensated voltage reference, sawtooth oscillator, error amplifier, pulse width modulator, pulse metering and steering logic, and two low impedance power drivers. Also included are protective features such as soft-start and undervoltage lockout, digital current limiting, double pulse inhibit, a data latch for single pulse metering, adjustable deadtime, and provision for symmetry correction inputs. For ease of interface, all digital control ports are TTL and B-series CMOS compatible. Active LOW logic design allows wired-OR connections for maximum flexibility.
Key Features: • 8 to 35 volt operation
5V reference trimmed to ±1%
1Hz to 350KHz oscillator range
Dual 100mA source/sink outputs
Digital current limiting
Double pulse suppression
Programmable deadtime
Temperature range of -55°C to +150°C.
Genuine Microsemi - New Old Stock - Rare
Package: 18 CDIP.
