Phase Shift Resonant Controller

FEATURES

DESCRIPTION

• Zero to 100% Duty Cycle Control

The UC1875 family of integrated circuits implements control of a bridge

power stage by phase-shifting the switching of one half-bridge with respect

to the other, allowing constant frequency pulse-width modulation in combi-

nation with resonant, zero-voltage switching for high efficiency performance

at high frequencies. This family of circuits may be configured to provide

control in either voltage or current mode operation, with a separate

over-current shutdown for fast fault protection.

• Programmable Output Turn-On Delay

• Compatible with Voltage or Current

Mode Topologies

• Practical Operation at Switching

Frequencies to 1MHz

A programmable time delay is provided to insert a dead-time at the turn-on

of each output stage. This delay, providing time to allow the resonant

switching action, is independently controllable for each output pair (A-B,

C-D).

• Four 2A Totem Pole Outputs

• 10MHz Error Amplifier

• Undervoltage Lockout

With the oscillator capable of operation at frequencies in excess of 2MHz,

overall switching frequencies to 1MHz are practical. In addition to the stan-

dard 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.

• Low Startup Current –150µA

• Outputs Active Low During UVLO

• Soft-Start Control

• Latched Over-Current Comparator

With Full Cycle Restart

Protective features include an undervoltage lockout which maintains all out-

puts in an active-low state until the supply reaches a 10.75V threshold.

1.5V 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 70nsec of a fault. The current-fault circuitry implements

• Trimmed Reference

full-cycle restart operation.
