Product Summary

The ISL6534CR is a versatile triple regulator that has two independent synchronous-rectified buck controllers with integrated 12V gate drivers (OUT1 and OUT2) and a linear controller (OUT3) to offer precision regulation of up to three voltage rails. An optional shunt regulator allows 12V only operation, when a 5V supply is not available.

Parametrics

ISL6534CR absolute maximum ratings: (1)Supply Voltage (VCC12): GND - 0.3V to 14.0V; (2)Supply Voltage (VCC, separate supply): GND - 0.3V to 5.5V; (3)Supply Voltage (VCC, shunt regulator): GND - 0.3V to 6.0V; (4)UGATE1, UGATE2, BOOT1, BOOT2: GND - 0.3V to 30V; (5)LGATE1, LGATE2, DRIVE3: GND - 0.3V to VCC12; (6)FS_SYNC (through 10K resistor): GND - 0.3V to 12V; (7)REFIN, REFOUT, PGOOD, VREF: GND - 0.3V to VCC; (8)FB1, COMP1, FB2, COMP2, FB3: GND - 0.3V to VCC; (9)SS1/EN1, SS2/EN2, SS3/EN3: GND - 0.3V to VCC; (10)PGND: GND - 0.3V to GND + 0.3V.

Features

ISL6534CR features: (1)Two Synchronous-Rectified Buck Controllers: Voltage Mode control VIN range up to 12V VOUT range from 0.6V to 6V 12V LGATE drivers; up to 12V Boot Strap for UGATE; (2)Switcher References: 0.6V Reference for OUT1 (0.8% Accurate) 3.3V Reference Output for OUT2 (0.8% Accurate) External Reference Input for OUT2 Buffered VTT Reference Output; (3)Switcher clocking: Phase options for Optimal Clock Relationship Resistor-Selectable Switching Frequency (300kHz; (4)default; Resistor to Ground for 300kHz to 1MHz range) Synchronization-Capable Switching Frequency (Connect FS_SYNC to Separate Regulator); (5)Single Linear Controller: Drives N-Channel MOSFET 0.6V Reference (0.8% Accurate) VIN range up to 12V VOUT range from 0.6V to 6V; (6)12V and 5V supplies required (but optional shunt regulator: can generate VCC = 5.8V from 12V); (7)Three Independent Soft-Start/Enable Pins: Gang Together or Control Independently.
