Product details
Overview
HIP6019BCB from Intersil is an advanced dual PWM and dual linear power control IC for microprocessor motherboard power regulation. It integrates two voltage-mode PWM controllers (for core and I/O rails), one linear regulator (2.5V @ 230mA), and one linear controller (1.5V @ external N-MOSFET), all in a single 28-lead SOIC package. Key confirmed parameters: ±1% core output regulation, 200kHz free-running oscillator (50–1000kHz programmable), 5-bit TTL DAC (1.3–3.5V core voltage selection), and MOSFET rDS(ON)-based over-current sensing.
For engineers reviewing the HIP6019BCB datasheet, HIP6019BCB pinout, HIP6019BCB application, or HIP6019BCB equivalent, this page delivers verified technical context, exact pin functions, real-world motherboard use cases, and validated alternative options - all grounded in the FN4587 Rev 1.00 datasheet and Intersil's official specifications.
Technical Context
The HIP6019BCB implements voltage-mode PWM control with high-bandwidth error amplifiers (15MHz GBWP, 6V/µs slew rate) and full 0–100% duty-cycle capability. Its dual PWM architecture uses synchronous rectification for the core rail (VOUT1) and standard buck topology for the I/O rail (VOUT2), while the linear regulator (VOUT4) and linear controller (VOUT3) operate independently with soft-start–clamped reference inputs.
Protection logic integrates four independent monitoring paths: VSEN1/VSEN2-based over-voltage detection (115% DACOUT for VOUT1, 4.3V for VOUT2), rDS(ON)-based over-current sensing via OCSET1/OCSET2 current sources (200µA typ), and FB3/FB4 under-voltage latching with 6% hysteresis. Fault response cycles soft-start three times before latching FAULT/RT to VCC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6018BCB | Single PWM + dual linear configuration; lacks second PWM channel and VID DAC - no core voltage programmability | Supports only fixed-core or externally controlled core rail; suitable for non-CPU applications like peripheral power | Select when only one adjustable PWM rail is required and VID interface is unnecessary |
| ISL6522CBZ | Single 3-phase CPU core controller with integrated MOSFET drivers; no I/O, linear regulator, or GTL controller functions | Optimized exclusively for high-current CPU core delivery; requires separate ICs for I/O, clock, and bus rails | Select for modern high-power CPUs where phase interleaving and higher current capability (>30A) are mandatory |
Compared with HIP6019BCB, HIP6018BCB sacrifices core voltage programmability and dual PWM flexibility for reduced complexity, while ISL6522CBZ trades multi-rail integration for superior CPU core current delivery and phase control - making HIP6019BCB uniquely suited for complete legacy motherboard power consolidation.

FAQ
What is the core voltage range supported by the HIP6019BCB DAC?
The HIP6019BCB DAC supports a core voltage range from 1.3VDC to 3.5VDC, with 0.05V steps between 1.3V and 2.05V, and 0.1V steps from 2.1V to 3.5V. This range is defined by the five VID pins (VID0–VID4) and enables precise microprocessor core voltage selection per Intel VID protocols. The HIP6019BCB datasheet (FN4587 Rev 1.00, Table 1) confirms all 32 combinations, including INHIBIT mode for shutdown.
Does the HIP6019BCB require external current-sense resistors for over-current protection?
No, the HIP6019BCB does not require external current-sense resistors. It uses the upper MOSFET's rDS(ON) and internal 200µA current sources (OCSET1/OCSET2) to detect over-current conditions. The equation IPEAK = (IOCSET × ROCSET) / rDS(ON) defines the trip point, eliminating power loss and board space associated with shunt resistors. This method is explicitly documented in the HIP6019BCB datasheet Section "Over-Current Protection".
What is the function of the FAULT/RT pin on the HIP6019BCB?
The FAULT/RT pin on the HIP6019BCB serves dual functions: it sets the oscillator switching frequency via an external RT resistor to GND (or VCC), and reports system faults by pulling to VCC during over-voltage or over-current events. During normal operation, its voltage is ~1.26V; during fault, it rises to near VCC to signal latch-up. This dual-role design reduces pin count and simplifies system-level fault monitoring - a key feature confirmed in the HIP6019BCB block diagram and functional description.
Can the HIP6019BCB regulate both synchronous and standard buck topologies simultaneously?
Yes, the HIP6019BCB simultaneously regulates a synchronous-rectified buck converter (for VOUT1/core rail using UGATE1/LGATE1) and a standard buck converter (for VOUT2/I/O rail using UGATE2 only). The first PWM channel drives both high-side and low-side MOSFETs, while the second uses only high-side drive with an external Schottky diode or optional low-side FET. This mixed-topology capability is explicitly stated in the HIP6019BCB datasheet introduction and Figure 3 schematic.
What is the maximum load current supported by the HIP6019BCB's integrated linear regulator?
The HIP6019BCB's integrated linear regulator (VOUT4) supports up to 230mA continuous output current, with regulation specified as 2.5V ±2.5% across 10mA to 150mA. The datasheet notes "230mA" as the over-current protection threshold, confirming safe operation up to that limit. This rail is intended for low-power clock driver circuits, not high-current loads - a design constraint clearly defined in the Electrical Specifications table on page 4 of the HIP6019BCB datasheet.
