Product details
Overview
IPM6220ACAZA-T from Intersil is an advanced triple PWM and dual linear power controller in a 24-lead SSOP package, delivering five regulated voltages (+5V ALWAYS, +3.3V ALWAYS, +5V Main, +3.3V Main, +12V) for notebook PC power systems. It integrates synchronous buck controllers (300kHz), a 100kHz boost converter, and linear regulators with input voltage feed-forward, current-mode control, and rDS(ON)-based current sensing.
For engineers reviewing the IPM6220ACAZA-T datasheet, IPM6220ACAZA-T pinout, IPM6220ACAZA-T application, or IPM6220ACAZA-T equivalent, key selection considerations include its ACPI-compatible shutdown logic (SDWNALL/SDWN1/SDWN2), out-of-phase buck operation for reduced input ripple, hysteretic light-load mode, Pb-free SSOP packaging, and battery-input operation from 5.6V to 24V.
Technical Context
The IPM6220ACAZA-T implements two 300kHz synchronous buck converters (5V Main and 3.3V Main) with current-mode control, input voltage feed-forward ramp modulation, and adaptive dead-time gate drivers-enabling fast transient response across wide line/load ranges. Its third channel is a 100kHz boost converter with fixed 33% maximum duty cycle and leading-edge PWM for stable 12V generation from the 5V Main rail.
It embeds dual low-current linear regulators (+5V ALWAYS and +3.3V ALWAYS) with combined 50mA output capability and internal MOSFET bypass (1.3Ω rDS(ON)) that switches to the 5V Main rail when active-reducing dissipation. Protection includes UVLO (4.7V turn-on, 300mV hysteresis), overtemperature shutdown (150°C), PGOOD monitoring with -12% threshold, and soft-crowbar OVP on main outputs.
Key Specifications

FAQ
What is the operating input voltage range for the IPM6220ACAZA-T?
The IPM6220ACAZA-T operates from 5.6V to 24.0V on the VBATT pin, covering standard Li-ion battery stacks (3–4 cells) and AC adapter inputs. Its UVLO turns the device on at 4.7V (±0.4V) with 300mV hysteresis, ensuring reliable startup across battery discharge curves. This range is validated per FN9032 Rev 1.00 Absolute Maximum and Recommended Operating Conditions tables.
How does the IPM6220ACAZA-T achieve high efficiency at light loads?
The IPM6220ACAZA-T achieves high light-load efficiency through automatic hysteretic mode operation: when inductor current becomes discontinuous, it disables continuous PWM switching and regulates output voltage via comparator-based pulse bursts. This reduces quiescent current to 300μA and eliminates switching losses during idle periods-confirmed in FN9032 Section "Light-Load (Hysteretic) Operation" and Electrical Specifications table.
Can the IPM6220ACAZA-T be used without external current sense resistors?
Yes, the IPM6220ACAZA-T uses the rDS(ON) of the lower MOSFETs as the primary current-sensing element for both buck converters, eliminating the need for external sense resistors. The ISEN1 and ISEN2 pins monitor the voltage drop across the MOSFETs' on-resistance. An optional external resistor may be added for tighter current-limit accuracy, as detailed in FN9032 Page 7 "Current Sensing and Current Limit Protection".
What is the function of the SDWNALL pin on the IPM6220ACAZA-T?
The SDWNALL pin is the global enable/disable control for the IPM6220ACAZA-T. When pulled low, it shuts down all outputs-including 3.3V ALWAYS and 5V ALWAYS-and reduces supply current to <1.0μA. When high (>2.4V), it enables the ALWAYS rails and permits SDWN1/SDWN2 to independently control the 5V Main and 3.3V Main outputs-supporting ACPI S0–S5 state transitions per FN9032 Table 1 and Functional Pin Descriptions.
Does the IPM6220ACAZA-T support power sequencing between its output rails?
Yes, the IPM6220ACAZA-T supports precise power sequencing via independent soft-start capacitors on SDWN1 and SDWN2 pins. Each pin sources a 5μA internal current, allowing RC time constants to delay 5V Main and 3.3V Main ramp-up relative to the ALWAYS rails. Sequencing order and timing are programmable per FN9032 Equation on Page 9 and Figure 7 waveform analysis.
