Output voltage control for SMPS2. All internal circuitry shuts down during thermal shutdown. The internal digital soft-start timer begins to ramp up the maximum-allowed current limit during start-up.

ISL6236 Buck Controller overview

Information furnished by Intersil is believed to be accurate and reliable. The configuration of the pin 1 identifier is optional, but must be located within the zone indicated. The ISL dual step-down, switch-mode power-supply.

This practice is essential for stable, jitter-free operation.

LDO can provide a total of mA external loads. Connect BYP to 3. This device features a linear regulator providing 3. Once activated, the controller continuously monitors the output for undervoltage and overvoltage fault conditions. Low-current applications usually require less attention.


Ensure the gate is not pulled up by the high-side switch turning datawheet due to parasitic drain-to-gate capacitance, causing cross-conduction problems. UVP is ignored for at least 20ms typicalafter start-up or after a rising edge on EN.

The synchronous-switch gate drivers are directly powered from PVCC, while the high-side switch gate drivers are indirectly powered from PVCC through an external capacitor and an internal Schottky diode boost circuit. The actual capacitance value required relates to the physical size needed to achieve low ESR, as well as to the chemistry of the capacitor technology. There is no switchover in adjustable mode. UVP only applies to the buck outputs.

Near the device, create a small analog ground plane. It is the “first line of defense” before OVP. The LDO regulate at 3. The top-side star ground is a star connection of the input capacitors and synchronous rectifiers. Wide Input Voltage Range 5. The ISL fatasheet switching regulator operates at different frequencies.

Extremely Low Component Count? RF interference in sensitive applications. The crossover point occurs at an even lower value if a swinging soft-saturation dahasheet is used. EN1 or EN2 falling below 1.

The ON-time one-shot triggers when the following conditions are met: Leave it open if there is no load. Forced-PWM mode is most useful for reducing audio-frequency noise, improving load-transient response, providing sink-current capability for dynamic output voltage adjustment, and improving the cross-regulation of multiple-output applications that use a flyback transformer or coupled inductor.

These actions bootstrap the device, powering the loads datasueet the BYP input voltages, rather than through internal linear regulators from the battery. Generally, low inductor values produce a broader efficiency vs load curve, while higher values result in higher FN Copyright Intersil Americas Inc.
