The linear regulator provides up to mA output current with automatic linear-regulator isl62236 to the BYP input. Connect to the SMPS2 output. Extremely Low Component Count? Information furnished by Intersil is believed to be accurate and reliable.
High-Efficiency, Quad-Output, Main Power Supply Controllers For Notebook Computers
These actions bootstrap the device, powering the loads from the BYP input voltages, rather than through internal linear regulators from the battery.
However, for high-current applications, some combinations of high- and low-side MOSFETs may cause excessive gate-drain coupling, which leads to poor efficiency and EMI-producing shoot-through currents. Connect to REF or leave floating for ultrasonic skip mode operation. 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.
Keep the high-current paths short, especially at the ground terminals. Ferrite cores are often the best choice. Also, total output ripple above 3.
Once activated, the controller continuously monitors the output for undervoltage and overvoltage fault conditions.

The controller utilize the valley point of the output ripple to regulate and determine the OFF-time.
Dimensions are in millimeters. Bypass LDO output with a minimum of 4. Reducing the CP decoupling capacitor and placing a small ceramic capacitor 10pF to 47pF in parallel with the upper leg of the SECFB resistor feedback network R1 of Figure 68will also increase the robustness of the charge pump. POK1 is low in shutdown. Switching frequency increases as a function of load current due to the increasing drop across the synchronous rectifier, which causes a faster inductor-current discharge ramp.

Intersil Electronic Components Datasheet. SMPS dattasheet generates logic-supply voltages in. A for external loads. Dimension b applies to the metallized terminal and is measured between 0.
It also serves as the SMPS1 feedback input in fixed-voltage mode. The linear regulator provides up to mA output current with automatic linear-regulator bootstrapping to the BYP input. Lower input voltages result in better efficiency. Does not apply in PFM mode see further details on page Drive EN2 below 0.

An ultrasonic pulse occurs when the controller detects that no switching has occurred within the last 20? Also, the dead-time effect increases the effective ON-time, reducing the switching frequency. Size and efficiency trade-offs must be considered when setting the inductor ripple current ratio.
The top-side star ground is a star connection of the input capacitors and synchronous rectifiers.
