Product details

Overview

IR1152SPBF from International Rectifier is a fixed-frequency (66 kHz) continuous conduction mode (CCM) boost-type power factor correction (PFC) IC implementing One Cycle Control (OCC) architecture, featuring average current mode control, brown-out protection (BOP), output overvoltage protection (OVP), and 750 mA peak gate drive for MOSFET switching in universal-input (85–264 VAC) offline PFC stages.

For engineers reviewing the IR1152SPBF datasheet, IR1152SPBF pinout, IR1152SPBF application, or IR1152SPBF equivalent, key selection criteria include its 66 kHz fixed oscillator frequency, <0.075 mA micropower startup/sleep current, BOP threshold of 0.78 V (typ), OVP reset at 103% VREF, and SO-8 package compatibility with industrial-grade thermal and ESD robustness (MSL2, Class 1A HBM).

Technical Context

The IR1152SPBF implements a dual-loop OCC architecture: a slow outer voltage loop (via VFB/COMP) generating a DC error signal (Vm) to regulate DC bus voltage, and a fast inner current loop using amplified ISNS feedback (gDC = 3.1 V/V, fC = 5 kHz) to shape input current sinusoidally without line-voltage sensing. The resettable integrator generates a PWM ramp with slope Vm × fSW.

Control logic includes cycle-by-cycle peak current limiting via ISNS threshold (−0.75 V), open-loop protection triggered at 19% VREF on VFB, latch-immune gate driver with 12–14 V high-side clamp, and UVLO hysteresis (VCC ON = 13.1 V, VCC UVLO = 10.1 V, Δ = 3 V) ensuring clean start-up and fault recovery.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	66 kHz fixed (53.8–73 kHz over −25°C to +125°C); eliminates external timing components and reduces audible noise in magnetics.
VCC Operating Range	14–17 V; requires external bias supply; no internal clamping - external Zener or regulator needed above 17 V.
Brown-Out Threshold	0.78 V (typ) on BOP pin; detects AC line drop below ~85 VAC and disables gate drive to prevent unstable operation.
OVP Reset Threshold	103% VREF (5.15 V typ); allows safe recovery after overvoltage event without full restart.
Startup Current	<75 µA at VCC = VCC_ON − 0.5 V; enables direct HV startup from rectified line via high-value resistor.
Gate Drive Peak Current	750 mA; sufficient to drive 10 nF gate capacitance with <65 ns fall time (CLOAD = 4.7 nF, VCC = 15 V).
Current Sense Threshold	−0.75 V (typ) on ISNS pin; sets peak inductor current limit with 170–470 ns blanking to reject switching noise.

Pinout & Package

The IR1152SPBF is housed in an industry-standard SO-8 surface-mount package (JEDEC MS-012AA), thermally rated for RθJA = 128°C/W and PD = 976 mW at TAMB = 25°C, qualified to Industrial level per JEDEC JESD47.

Pin/Terminal	Circuit Role	Design Meaning
1 COM	Power Ground Reference	Primary return path for ISNS, VFB, COMP, BOP, OVP/EN; must be low-inductance connection to power ground plane.
2 COMP	Voltage Loop Compensation Node	Output of internal error amplifier; connects external RC network to set bandwidth and phase margin of outer voltage loop.
3 ISNS	Current Sense Input	Accepts negative voltage from shunt resistor; −0.75 V threshold triggers cycle-by-cycle current limit; blanked for 320 ns (typ).
4 BOP	Brown-Out Detection Input	Monitors scaled AC line voltage; asserts fault when input falls below 0.78 V (typ), disabling gate drive until recovery.
5 OVP/EN	OVP Fault Input / Sleep Mode Enable	Pulled low (<0.8 V) to enter micropower sleep mode (<75 µA); also monitors VFB-derived OVP signal for DC bus overvoltage.
6 VFB	Output Voltage Feedback Input	Resistive divider from DC bus connects here; 5 V reference used to detect 106% overvoltage and 19% open-loop condition.
7 VCC	IC Supply Voltage Input	14–17 V operating range; UVLO activates below 10.1 V; no internal clamp - external protection required above 20 V.
8 GATE	MOSFET Gate Driver Output	750 mA sink/source; drives N-channel MOSFET gate; clamped to 14 V max; fault pulls to 0.08 V to indicate shutdown.

Key Features

Feature	Design Value
One Cycle Control (OCC) Algorithm	Eliminates need for AC line voltage sensing by deriving current reference from inductor current waveform, reducing component count and improving PF >0.99 at full load.
Fixed 66 kHz Oscillator	Integrated timing core ensures jitter-free gate drive and immunity to noise coupling - critical for EMI compliance and acoustic noise suppression.
Micropower Sleep Mode	User-initiated via OVP/EN pin <0.8 V; draws <75 µA while retaining state - meets IEC 62301 standby power requirements.
Average Current Mode Sensing	On-chip RC filter (fC = 5 kHz) rejects switching ripple while tracking 120 Hz rectified current, enabling stable control with small boost inductors (≤40% ripple).
Robust Protection Suite	Includes BOP, OVP, open-loop detection, cycle-by-cycle current limit, UVLO, and latch-immune driver - enables single-chip fault management without external supervisors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PFC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
UCC28070DR	Interleaved dual-channel CCM controller; 65–125 kHz programmable frequency; no integrated BOP comparator - requires external sensing.	Targeted at higher-power (>500 W), lower-THD systems where interleaving reduces input/output ripple and EMI filtering cost.	Select UCC28070DR when interleaved operation, programmable frequency, or multi-phase coordination is required; IR1152SPBF preferred for cost-sensitive, single-phase, fixed-frequency designs.
FAN6982MY	Fixed 65 kHz frequency; valley-switching quasi-resonant control; lower gate drive (500 mA); no OVP/EN sleep mode - only UVLO-based disable.	Optimized for QR PFC topologies with lower switching loss; lacks micropower sleep and BOP - unsuitable for brownout-prone environments.	Choose FAN6982MY for efficiency-critical QR designs with stable AC input; IR1152SPBF remains superior for universal-line applications needing BOP, OVP, and sub-75 µA sleep.

Compared with UCC28070DR and FAN6982MY, the IR1152SPBF uniquely integrates brown-out detection, user-controllable sleep mode, and OCC-based simplicity - delivering lowest BOM count and fastest design cycle for single-phase CCM PFC in 85–264 VAC systems.

FAQ

What is the minimum VCC voltage required to exit UVLO and begin normal operation?

The IR1152SPBF exits UVLO when VCC rises above the turn-on threshold of 13.1 V (typical), with hysteresis of 3 V ensuring stable re-enabling. Below 10.1 V (typical UVLO threshold), the IC halts gate drive and enters low-current state. External bias must sustain VCC ≥14 V during steady-state operation.

How does the brown-out protection (BOP) function differ from standard undervoltage lockout (UVLO)?

BOP monitors AC line voltage via the BOP pin using a dedicated comparator with 0.78 V threshold, triggering immediate gate disable during sustained line sags - independent of VCC. UVLO protects the IC's internal circuitry from insufficient supply voltage. BOP enables system-level line monitoring without additional circuitry.

Can the IR1152SPBF be used with SiC or GaN MOSFETs, and what gate drive limitations apply?

Yes - its 750 mA peak gate drive and 14 V internal clamp support fast switching of SiC/GaN devices with ≤10 nF total gate charge. However, the 66 kHz fixed frequency limits high-frequency optimization; gate resistor selection must balance switching loss vs. EMI, and layout must minimize ISNS and GATE loop inductance to preserve blanking integrity.

What is the role of the COMP pin, and how is compensation network design affected by the OCC architecture?

The COMP pin outputs the error amplifier's transconductance-stage voltage (gm = 49 µS typical), which sets the amplitude of the resettable integrator's ramp. Compensation uses a Type II network (series RC + shunt capacitor) to stabilize the outer voltage loop; bandwidth must remain <10 Hz to reject 120 Hz ripple while ensuring phase margin >45° at crossover.
