FN6708.0

PWM DC/DC Voltage Regulator Controller

Features

The ISL62870 IC is a Single-Phase Synchronous-Buck

PWM voltage regulator featuring Intersil’s Robust Ripple

Regulator (R ) Technology™. The ISL62870 provides a low

• Input Voltage Range: 3.3V to 25V

• Output Voltage Range: 0.5V to 3.3V

• Output Load to 30A

cost solution for compact high performance applications.The

wide 3.3V to 25V input voltage range is ideal for systems

that run on battery or AC adapter power sources. Resistor

programmed output voltage setpoint and capacitor

programmed soft-start delay allow for fast and easy

implementation. Robust integrated MOSFET drivers and

Schottky bootstrap diode reduce the implementation area and

lower component cost.

• Simple Resistor Programming for Output Voltage

• ±0.75% System Accuracy: -10°C to +100°C

• Capacitor Programming for Soft-Start Delay

• Fixed 300kHz PWM Frequency in Continuous Conduction

• External Compensation Affords Optimum Control Loop

Tuning

Intersil’s R Technology™ combines the best features of

• Automatic Diode Emulation Mode for Highest Efficiency

both fixed-frequency and hysteretic PWM control. The PWM

frequency is 300kHz during static operation, becoming

variable during changes in load, setpoint voltage, and input

voltage when changing between battery and AC adapter

power. The modulators ability to change the PWM switching

frequency during these events in conjunction with external

loop compensation produces superior transient response.

For maximum efficiency, the converter automatically enters

diode-emulation mode (DEM) during light-load conditions

such as system standby.

• Integrated High-Current MOSFET Drivers and Schottky

Boot-Strap Diode for Optimal Efficiency

• Choice of Overcurrent Detection Schemes

- Lossless Inductor DCR Current Sensing

- Precision Resistive Current Sensing

• Power-Good Monitor for Soft-Start and Fault Detection

• Fault Protection

- Undervoltage

- Overvoltage

Pinout

- Overcurrent (DCR-Sense or Resistive-Sense Capability)

- Over-Temperature Protection

- Fault Identification by PGOOD Pull-Down Resistance
