POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description/ordering information
With the oscillator capable of operation at frequencies in excess of 2 MHz, overall switching frequencies to
1 MHz are practical. In addition to the standard free running mode, with the CLOCKSYNC pin, the user may
configure these devices to accept an external clock synchronization signal, or may lock together up to 5 units
with the operational frequency determined by the fastest device.
Protective features include an undervoltage lockout which maintains all outputs in an active-low state until the
supply reaches a 10.75 V threshold. 1.5 V hysteresis is built in for reliable, boot-strapped chip supply.
Over-current protection is provided, and will latch the outputs in the OFF state within 70 ns of a fault. The
current-fault circuitry implements full-cycle restart operation.
Additional features include an error amplifier with band-width in excess of 7 MHz, a 5 V reference, provisions
for soft-starting, and flexible ramp generation and slope compensation circuitry.
This device is available in 28-pin “bat-wing” SOIC plastic package for operation over 25
°C to +110°C operation.
