Product details

Overview

IR1153SPBF from Infineon Technologies (formerly International Rectifier) is a fixed-frequency, average current mode PFC controller IC implementing One Cycle Control (OCC) for continuous conduction mode boost converters. It operates at 22.2 kHz (typ), delivers 750 mA peak gate drive, features brown-out protection (VBOP = 0.76 V), OVP/EN pin-controlled sleep mode (<75 µA), and VFB-referenced 5.0 V internal reference.

For engineers reviewing the IR1153SPBF datasheet, IR1153SPBF pinout, IR1153SPBF application in CCM boost PFC, or IR1153SPBF equivalent for industrial AC-DC front-end designs, this page provides verified functional context, validated pin roles, real-world protection thresholds, and confirmed alternative selection guidance.

Technical Context

The IR1153SPBF implements IR's proprietary One Cycle Control algorithm using a resettable integrator architecture with dual-loop control: a slow outer voltage loop (VFB → VCOMP error amplifier) regulating DC bus voltage, and a fast inner current loop (ISNS → current amplifier → PWM comparator) shaping input current to track rectified line voltage without direct AC line sensing.

Its fixed 22.2 kHz oscillator eliminates external timing components and jitter-sensitive digital calibration; the integrated current amplifier (gDC = 5.65 V/V, fC = 2 kHz) enables robust averaging of high-ripple inductor current (up to 40% ripple ratio), supporting compact boost inductors while maintaining THD < 5% and PF > 0.98 in compliant designs.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	22.2 kHz fixed - eliminates external RC timing network, reduces EMI spread, avoids audible magnetics noise
VREF Accuracy	4.9–5.1 V - enables precise 400 V DC bus regulation via VFB feedback with ±0.4% temp stability
Brown-Out Threshold	0.76 V (typ) on BOP pin - triggers shutdown when AC line drops below ~85 VAC (with proper resistive divider)
OVP Reset Hysteresis	VOVP(RST) = 103% VREF - prevents oscillation during overvoltage recovery; requires external resistor divider for 420 V DC trip
Start-up Current	<75 µA - supports high-impedance VCC bootstrap circuits; enables micropower auxiliary supply design
Peak Gate Drive	750 mA - directly drives MOSFET gates up to 2 kW PFC stages without external buffer
Sleep Mode Current	<75 µA - activated by pulling OVP/EN pin <0.8 V; meets IEC 62301 standby power limits

Pinout & Package

IR1153SPBF is housed in an SO-8 (SOIC-8) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant, MSL2 rated, and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
COM (Pin 1)	Power Ground Reference	Primary return path for ISNS, VFB, COMP, and internal bias; must be low-inductance connection to power ground plane
BOP (Pin 4)	Brown-Out Protection Input	Monitors scaled AC line voltage; asserts protection when voltage falls below 0.76 V (typ); high-impedance input (IBOP < 0.2 µA)
VFB (Pin 6)	Voltage Feedback Input	Connects to DC bus divider; regulates output voltage via 5.0 V internal reference; bias current < 0.2 µA
VCC (Pin 7)	Supply Voltage Input	Accepts 14–17 V; UVLO turn-on at 13.1 V (typ), hysteresis 3 V; no internal clamp - external Zener required above 20 V
GATE (Pin 8)	High-Current Gate Driver Output	Drives N-channel MOSFET gate with 750 mA sink/source; rise/fall times < 65 ns into 4.7 nF load
ISNS (Pin 3)	Current Sense Input	Accepts negative-going voltage across sense resistor; peak limit threshold = –0.51 V (typ); blanking time = 320 ns (typ)
COMP (Pin 2)	Error Amplifier Output	Integrator node for voltage loop; start voltage = 210–435 mV; fault level = 1.5 V; used for loop compensation
OVP/EN (Pin 5)	Overvoltage Input / Sleep Enable	Double-function pin: detects overvoltage (106% VREF) or initiates sleep mode when pulled < 0.8 V

Key Features

Feature	Design Value
One Cycle Control (OCC) Algorithm	Eliminates need for AC line voltage sensing and multi-pole compensation; achieves PF > 0.98 and THD < 5% with single-loop tuning
Fixed 22.2 kHz Oscillator	Integrated timing core removes external components, ensures jitter-free gate drive, and suppresses audible transformer noise
Programmable Soft Start	Configurable via RGAIN and CZERO (e.g., 35 ms delay with 8 kΩ/0.33 µF); prevents inrush current and output overshoot
Input-Line Sensed Brown-Out Protection	Detects low-line conditions directly from rectified AC via BOP pin - no secondary-side monitoring required
User-Initiated Sleep Mode	Reduces total system standby consumption to <100 µA by asserting logic-low on OVP/EN; compatible with 3.3 V/5 V microcontrollers

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
UCC28070PW	Interleaved dual-channel CCM controller; 65–300 kHz programmable frequency; no built-in brown-out sense pin	Requires external brown-out circuit; suited for higher-power (>3 kW), lower-THD systems with interleaving benefits	Select for multi-phase PFC where size/efficiency trade-off favors two smaller inductors over one large boost choke
FAN4803SJX	Fixed 65 kHz frequency; average current mode; no sleep mode; VCC UVLO only (no BOP/OVP pins)	Lacks line-sensed brown-out and user-initiated sleep; relies on system-level enable signals for standby	Choose when cost sensitivity outweighs feature requirements and board space allows discrete OVP/BOP implementation

Compared with UCC28070PW and FAN4803SJX, IR1153SPBF uniquely integrates brown-out detection, OVP/EN dual-function pin, and sub-75 µA sleep mode - making it optimal for cost-constrained, single-stage, industrial-grade PFC designs needing autonomous line-fault response and regulatory standby compliance.

FAQ

What is the purpose of the OVP/EN pin on IR1153SPBF?

The OVP/EN pin serves two distinct functions: (1) Overvoltage protection input - triggers latch-off when voltage exceeds 106% of VREF (5.0 V); (2) Sleep mode enable - pulls the IC into micropower state (<75 µA) when held below 0.8 V. Both functions share the same pin but operate independently based on voltage threshold crossing.

How does IR1153SPBF achieve power factor correction without sensing the AC input voltage?

It uses One Cycle Control with inherent line-voltage tracking: the ISNS signal (boost inductor current) contains the sinusoidal envelope of the rectified line voltage. The current amplifier and resettable integrator process this signal to generate a proportional current reference - eliminating need for separate AC voltage sensing circuitry or multiplier ICs.

Can IR1153SPBF operate with a 400 V DC bus and 90–264 VAC input range?

Yes - configured with appropriate VFB divider (e.g., 1 MΩ + 12.1 kΩ for 400 V), BOP resistor network (e.g., 100 kΩ + 10 kΩ for 85 VAC brown-out), and ISNS sense resistor (e.g., 10 mΩ for 10 A peak), it fully supports universal input and regulated 400 V DC bus per IEC 61000-3-2 Class C requirements.

What thermal derating applies to IR1153SPBF in SO-8 package at 70°C ambient?

With RθJA = 128 °C/W and max TJ = 150 °C, allowable power dissipation at 70°C ambient is (150 − 70) / 128 ≈ 625 mW. Since typical ICC is 5 mA at 15 V (75 mW), thermal margin is ample; PCB copper area and airflow have negligible impact on junction temperature in normal operation.
