Product details

Overview

ICE1CS02GXUMA2 from Infineon Technologies is a dual-stage off-line SMPS controller integrating average-current-mode PFC and current-mode PWM in a single IC. It delivers 65 kHz fixed-frequency PFC control with 95% max duty cycle and 130 kHz synchronizable PWM output, supporting Class D IEC 61000-3-2 compliance. Its 1.5 A source / 2.0 A sink gate drivers, ±2.5% trimmed 5 V reference (VREF), and dual brown-out protection enable robust AC-DC power supplies up to 300 W.

For engineers reviewing the ICE1CS02GXUMA2 datasheet, ICE1CS02GXUMA2 pinout, ICE1CS02GXUMA2 application, or ICE1CS02GXUMA2 equivalent, key selection criteria include PFC/PWM frequency ratio (1:2), external duty-cycle selection via PWM SYNC pin, integrated pre-short blanking, soft-start timing (12 ms), and dual-loop compensation at PFC ICOMP/VCOMP pins.

Technical Context

The ICE1CS02GXUMA2 implements a two-channel architecture: the PFC section uses average-current-mode control with internal ramp generation and nonlinear gain for dynamic response, while the PWM section employs peak-current-mode control with leading-edge blanking (220 ns) and slope compensation activated when VSYNC < 3.0 V. Both sections share a common ground and VCC supply (11–26 V).

It features synchronized oscillator operation (PFC:PWM = 1:2), dual brown-out detection (VINS/VINS_HYS), and independent protection blocks - including overvoltage (3 V threshold at PFC OVP), open-loop (OLP), and pre-short (capacitor-set blanking time). The 5 V VREF pin serves as both reference output and PWM enable/disable control.

Key Specifications

Parameter	Value and Actual Design Meaning
PFC Switching Frequency	65 kHz fixed, synchronized to PWM clock; enables predictable EMI filtering and transformer design.
PWM Switching Frequency	130 kHz fixed, externally synchronizable from 70–150 kHz; supports multi-controller systems and noise spreading.
Max PFC Duty Cycle	95% typical; allows high boost ratio operation with low input voltage (e.g., 85 VAC universal input).
Max PWM Duty Cycle	Selectable 47% or 60% via resistor on PWM SYNC pin; ensures safe operation under overvoltage (≥330 V bus).
VREF Output	5.0 V ±2.5%, 12 mA sourcing capability; powers optocoupler bias and enables PWM shutdown when pulled low.
Gate Drive Strength	1.5 A source / 2.0 A sink per output (PFC OUT, PWM OUT); drives MOSFETs up to 1 nF gate charge without external buffers.
Current Sense Threshold	Internal comparator trips at 1.0 V on PWM CS and PFC ISENSE; sets precise overcurrent limit with minimal external components.

Pinout & Package

ICE1CS02GXUMA2 is housed in a PG-DIP-16-4 through-hole package (16-pin dual in-line, 0.6 inch width) with standard 2.54 mm pitch and RoHS-compliant lead plating.

Pin/Terminal	Circuit Role	Design Meaning
1 PFC ICOMP	Current Loop Compensation	Integrates OTA2 output to stabilize average-current regulation; connects RC network for loop tuning.
2 PFC VSENSE	VBUS Voltage Feedback	Senses output DC bus via resistive divider; 3 V reference enables 390–400 V regulated output.
3 PFC OVP	Overvoltage Protection Input	Triggers shutdown if VBUS exceeds 3 V threshold (e.g., >400 V); prevents capacitor overvoltage failure.
4 PFC VCOMP	Voltage Loop Compensation	Hosts compensation network for output voltage loop; also controls soft-start ramp rate.
5 GND	Controller Ground	Common return for analog and power sections; must be low-impedance to avoid noise coupling.
6 PFC OUT	PFC Gate Driver Output	Drives PFC switch MOSFET gate; clamped at 15 V to protect gate oxide.
7 VCC	Supply Voltage Input	Accepts 11–26 V auxiliary supply; internal UVLO prevents erratic operation below 11 V.
8 PWM OUT	PWM Gate Driver Output	Drives PWM stage MOSFET gate; identical drive strength and clamp to PFC OUT.
9 PWM CS	PWM Current Sense Input	Detects primary-side current for peak-current-mode control and overcurrent shutdown.
10 PWM SYNC/Duty Cycle	Sync Input & Max Duty Control	Accepts external clock (70–150 kHz) or sets 47%/60% max duty via resistor to VCC.
11 PWM PreShort	Pre-short Blanking Time	Capacitor-connected pin sets blanking duration (e.g., 30 µs) before short-circuit detection.
12 PWM FB	PWM Feedback Input	Receives optocoupler signal to regulate secondary-side output voltage.
13 VREF	5 V Reference Output	Stable 5 V rail for biasing; pulling low disables PWM output with soft restart.
14 VINS HYS	Brown-Out Hysteresis Output	Provides comparator output to set hysteresis between VINS trip points using external resistor.
15 VINS	AC Input Voltage Sense	Detects rectified line voltage; initiates brown-out shutdown if input drops below set threshold.
16 PFC ISENSE	PFC Current Sense Input	Measures boost inductor current for average-current control and peak limiting.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE2PCS01G	Single-channel PFC-only controller; requires external PWM IC; higher VCC UVLO (13.5 V).	No integrated PWM stage; increases component count and timing complexity for dual-stage designs.	Select when PFC performance is prioritized over integration and board space is not constrained.
UCC28070	Interleaved PFC controller with no native PWM channel; supports 2-phase operation; 12-bit DAC for voltage reference.	Designed for >500 W applications with interleaving; lacks synchronous PWM output and pre-short protection.	Choose for high-power (>400 W), low-THD systems where interleaving reduces input ripple and EMI.

Compared with ICE2PCS01G and UCC28070, ICE1CS02GXUMA2 uniquely integrates synchronized PFC/PWM timing, pre-short blanking, and dual brown-out detection in one package-reducing system-level design effort and improving startup reliability in cost-sensitive 100–300 W applications.

FAQ

What is the purpose of the VINS and VINS_HYS pins?

VINS senses the rectified AC input voltage to trigger brown-out protection when the line drops below a user-defined threshold. VINS_HYS provides the comparator output used with an external resistor to set hysteresis-ensuring the controller does not oscillate near the trip point during marginal line conditions. This dual-pin arrangement enables precise, stable brown-out behavior across temperature and supply variations.

How does the PWM SYNC pin support both synchronization and duty cycle selection?

PWM SYNC is a dual-function pin: applying an external clock signal (70–150 kHz) overrides the internal oscillator for synchronization, while connecting a resistor from this pin to VCC selects either 47% or 60% maximum PWM duty cycle. The IC automatically reverts to 47% if the sensed output voltage exceeds 330 V, ensuring safety compliance regardless of configuration.

Can the ICE1CS02GXUMA2 operate without external compensation components?

No-external RC networks are required at PFC ICOMP, PFC VCOMP, and PWM FB pins to stabilize both current and voltage control loops. The datasheet provides design equations and example values (e.g., 1 nF + 10 kΩ at PFC VCOMP) for Class D-compliant operation. Omitting these results in instability, overshoot, or failure to regulate.

What protection features are implemented in hardware versus those requiring external circuitry?

Hardware-implemented protections include UVLO (VCC), overvoltage (PFC OVP), pre-short blanking (PWM PreShort), and leading-edge blanking (PWM CS). External circuitry is required for PFC OVP and PWM FB feedback dividers, VINS brown-out threshold setting, and PFC ISENSE current-sense resistor. No external latch or shutdown logic is needed-the IC handles fault recovery autonomously via soft-start.
