SG1526/SG2526/SG3526

REGULATING PULSE WIDTH MODULATOR

DESCRIPTION

FEATURES

• 8 to 35 volt operation

The SG1526 is a high performance monolithic pulse width modulator

circuit designed for fixed-frequency switching regulators and other

power control applications. Included in 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. This versatile device can be used to implement

single-ended or push-pull switching regulators of either polarity, both

transformerless and transformer coupled. The SG1526 is characterized

for operation over the full military ambient junction temperature range of

-55°C to +150°C. The SG2526 is characterized for operation from -25°C

to +150°C, and the SG3526 is characterized for operation from 0°C to

+125°C.

• 5V reference trimmed to ±1%

• 1Hz to 350KHz oscillator range

• Dual 100mA source/sink outputs

• Digital current limiting

• Double pulse suppression

• Programmable deadtime

• Undervoltage lockout

• Single pulse metering

• Programmable soft-start

• Wide current limit common mode range

• TTL/CMOS compatible logic ports

• Symmetry correction capability

• Guaranteed 6 unit synchronization
