Product details

Overview

IR1150IPBF from Infineon Technologies is a continuous conduction mode (CCM) boost-type power factor correction (PFC) control IC implementing proprietary One Cycle Control (OCC), eliminating line voltage sensing, supporting 50–200 kHz programmable switching frequency, and delivering <200 µA sleep-mode current. It drives external MOSFETs in AC-DC front-end stages for industrial SMPS and LED drivers.

For engineers reviewing the IR1150IPBF datasheet, IR1150IPBF pinout, IR1150IPBF application, or IR1150IPBF equivalent, key selection criteria include its OCC-based current-loop architecture, OVP/EN dual-function pin behavior, gate drive capability (±1.5 A peak), and thermal derating limits across SOIC-8 packaging.

Technical Context

The IR1150IPBF implements a two-loop control system: a fast inner current loop that shapes input current without line voltage sensing, and an outer voltage loop regulating DC bus via VFB feedback with transconductance error amplifier (gm = 40 µS). The OCC technique embeds line voltage dependency directly into duty-cycle generation.

Protection is integrated at silicon level: cycle-by-cycle ISNS-based peak current limit (VISNS threshold = –1.04 V), brownout detection (VCC UVLO = 10.7 V), output overvoltage protection (VOVP = 105.5% VREF), and open-loop fault detection (VOLP = 19% VREF), all with defined hysteresis and blanking (TBLANK = 350 ns).

Key Specifications

Parameter	Value and Actual Design Meaning
Control Method	One Cycle Control (OCC) - eliminates need for line voltage sensing and reduces component count
Switching Frequency	50–200 kHz programmable via external resistor - enables EMI optimization and magnetics sizing
Gate Drive Output	±1.5 A peak, 13 V clamped - directly drives medium-power MOSFETs without external buffers
Sleep Mode Current	125–200 µA - meets Energy Star 1W standby and Blue Angel low-power requirements
Voltage Reference	7.0 V ±1% - stable reference for OVP, UVP, and feedback scaling across temperature
Current Sense Threshold	–1.04 V typical at ISNS - sets precise peak inductor current limit independent of VCC
Min Off Time	300 ns typical - ensures reliable minimum dead time at high switching frequencies
Thermal Resistance	128 °C/W (SOIC-8) - defines maximum power dissipation (675 mW at 25°C ambient)

Pinout & Package

IR1150IPBF is housed in an 8-pin SOIC package with exposed pad (RoHS-compliant, Pb-free). Pin functions are electrically isolated per internal block diagram and validated against Infineon's PD60230 revC datasheet.

Pin/Terminal	Circuit Role	Design Meaning
1 COM	Ground reference	Common return for all internal circuits; must be low-impedance connection to power ground plane
2 VCC	Supply input	Unclamped 15–18 V supply; UVLO turn-on at 12.7 V, turn-off at 10.7 V with 2 V hysteresis
3 ISNS	Current sense input	Inverting input for peak current limit; accepts –1.04 V threshold signal from shunt resistor
4 FREQ	Frequency programming	Resistor-to-ground sets fSW from 50–200 kHz; internal oscillator accuracy ±5% at 25°C
5 VFB	Voltage feedback input	Inverting input of transconductance error amplifier; monitors DC bus via resistive divider
6 OVP/EN	Overvoltage detect / Sleep enable	Triggers latch-off at 105.5% VREF; pulls <0.62 V to enter micropower sleep mode
7 GATE	High-side gate driver output	1.5 A peak totem-pole output; internally clamped to 13 V; rise/fall <70 ns with 10 nF load
8 COMP	Voltage loop compensation	Error amplifier output; discharges during fault; connects to RC network for loop stability and soft-start timing

Key Features

Feature	Design Value
No line voltage sensing required	Reduces BOM by ≥2 HV resistors and associated filtering; improves noise immunity in high-dV/dt environments
Programmable output overvoltage protection	Fixed 105.5% VREF threshold with 450 mV hysteresis - prevents bus capacitor over-stress during load dump or regulation loss
User-initiated micropower sleep mode	Active when OVP/EN < 0.62 V - reduces total system standby consumption below 200 µA without external controllers
Internal 13 V gate drive clamp	Enables direct drive of standard logic-level MOSFETs while preventing gate oxide overstress under transient VCC conditions
Leading-edge blanking on ISNS	350 ns fixed blanking window - suppresses switching noise false triggering of current limit comparator

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 CCM controller with dual-channel outputs; requires line voltage sensing; higher component count	Targeted for >750 W systems needing lower ripple and thermal spreading	Choose when interleaving is required; avoid if single-phase simplicity and cost reduction are priorities
FAN6300MX	CRM/DCM-only PFC controller; no CCM support; lacks programmable OVP and sleep mode	Suitable only for sub-300 W applications with relaxed THD requirements	Choose only for cost-sensitive, low-power lighting where CCM operation and standby compliance are not needed

Compared with UCC28070DR and FAN6300MX, IR1150IPBF uniquely delivers CCM operation without line sensing, integrated sleep mode, and single-chip protection - making it optimal for 300–600 W universal-input designs prioritizing BOM reduction and regulatory compliance.

FAQ

What is the purpose of the OVP/EN pin beyond overvoltage protection?

The OVP/EN pin serves a dual function: it triggers latch-off when voltage exceeds 105.5% VREF for overvoltage protection, and initiates micropower sleep mode when pulled below 0.62 V. In sleep mode, total supply current drops to 125–200 µA while maintaining full fault detection readiness - enabling compliance with Energy Star and Blue Angel standby power mandates without auxiliary circuitry.

How does One Cycle Control eliminate the need for line voltage sensing?

One Cycle Control embeds line voltage dependency directly into the pulse-width modulator's duty-cycle calculation using the inherent relationship between input voltage and boost inductor volt-second balance. The inner current loop reconstructs the sinusoidal reference from the instantaneous duty cycle and sensed inductor current, removing the need for external HV resistors, dividers, or filtering - reducing component count by up to 40% versus traditional average-current-mode controllers.

What is the maximum recommended gate capacitance for direct drive with IR1150IPBF?

The IR1150IPBF gate driver supports ≤10 nF total capacitive load while maintaining specified rise/fall times (<70 ns) and peak current (±1.5 A). For MOSFETs with gate charge >60 nC (e.g., IPW60R099P7), external buffer drivers are recommended to ensure reliable switching speed and prevent thermal stress on the IC's totem-pole output stage.

Does IR1150IPBF support automatic restart after UVLO or fault conditions?

No - IR1150IPBF uses a latch-off protection architecture. After UVLO dropout (VCC < 10.7 V) or fault-triggered shutdown (e.g., OVP, OLP), the IC remains disabled until VCC re-rises above 12.7 V and VFB exceeds 20% VREF, initiating soft start. This ensures safe, controlled recovery without unregulated bursts of gate drive - critical for reliability in high-energy boost stages.
