ILC6390 overview
ILC6390 is a component documented by Impala Linear Corporati. The PDF description identifies it as "SOT-89 STEP-UP PFM SWITCHER WITH AUTO-LOAD SENSE." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Normal operation is 55% duty at 155kHz; when load currents exceed the internal com- parator trip point, a “turbo mode” kicks in to provide extend- ed on-time switching (75% duty at 100kHz oscillation).
- Requiring only 30µA of supply current, the ILC6390 achieves efficiencies as high as 85% at 5V yet shuts down to 0.5µA max.
- Standard voltages offered are 2.5, 3.3, and 5.0V and is available in both a 5 lead SOT-23 and 5 lead SOT-89 pack- age for small footprint applications.
- The switching frequency is determined by the delay time of the internal comparator and MFO1, which sets the min.
- P L = ƒ(tON, VIN) The ILC6390 and ILC6391 use a PFM or Pulse Frequency Modulation technique.
- In this technique, the switch is always turned on for a fixed period of time, corresponding to a fixed switching frequency at a predefined duty cycle.
- For the ILC6390 this value is 3.55msec on time, corresponding to 55% duty cycle at 155kHz.
Topics covered by the datasheet
The document includes sections related to:
- Applications
- Ordering Information
Engineering review checklist
- Check voltage, continuous and pulsed current, safe operating area and junction-temperature limits.
- Evaluate conduction and switching losses using the specified drive conditions rather than headline ratings.
- Confirm pinout, package thermal path, gate or base protection and transient derating in the final circuit.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
