Product details
Overview
IDP2308XUMA1 from Infineon Technologies is a digital multi-mode PFC + LLC combo controller in PG-DSO-14 package, integrating 600 V HV startup cell, floating high-side gate driver (HSGD), and UART-configurable OTP memory. It delivers synchronous burst-mode control for <30 mW standby power, supports 75–300 W LCD-TV SMPS, and implements configurable non-linear VCO curve and X-cap discharge via HV pin.
For engineers reviewing the IDP2308XUMA1 datasheet, IDP2308XUMA1 pinout, IDP2308XUMA1 application, or IDP2308XUMA1 equivalent, key selection criteria include integrated HV startup eliminating auxiliary supply, dual current-sense inputs (CS0/CS1) for PFC+LLC stage monitoring, UART-based in-circuit configuration, and OTP-programmable soft-start and protection thresholds.
Technical Context
The IDP2308XUMA1 embeds a 66 MHz NanoDSP processor executing independent PFC and half-bridge LLC control loops with real-time adaptive algorithms. Its digital engine enables multi-mode operation-transitioning between CCM, CRM, and DCM for PFC, and TCO-to-VCO smooth frequency shift for LLC-optimized across full load range.
It integrates dedicated analog front-ends: ZCD for PFC zero-crossing detection, VS for bus voltage sensing, MFIO as half-duplex UART interface (also usable for PFC ROVP), and HBFB for optocoupler feedback. Protection includes PFCOCLP, PFCCCMP, LLCOCLP, LLCOLP, and thermal shutdown with auto-restart.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital PFC+LLC combo controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28070DWR | Analog dual-channel PFC+LLC controller; no integrated HV startup, no UART, no OTP, no floating HSGD. | Requires external HV startup circuit, separate gate drivers, and fixed protection thresholds; lower design flexibility. | Select when cost sensitivity outweighs programmability and standby power targets. |
| ICE2PCS01G | Fixed-function digital PFC-only IC; no LLC control, no HSGD, no MFIO interface. | Must pair with discrete LLC controller (e.g., IRS2795), increasing board area and component count. | Select only for PFC-only designs where LLC stage is handled separately. |
Compared with UCC28070DWR and ICE2PCS01G, IDP2308XUMA1 uniquely integrates HV startup, floating HSGD, UART-configurable OTP, and synchronous burst mode-enabling single-chip 75–300 W PFC+LLC designs with <30 mW standby and no auxiliary supply.

FAQ
What is the purpose of the HV pin on IDP2308XUMA1?
The HV pin serves three confirmed functions: (1) powering the internal 600 V startup cell to charge VCC at power-on, (2) discharging EMI X-capacitors after AC removal via internal HV switch, and (3) sampling AC line voltage for brown-in/brown-out detection. It connects externally to the AC input through a resistor-diode network per Figure 1 in the datasheet.
Does IDP2308XUMA1 require an external crystal or oscillator?
No. IDP2308XUMA1 contains an internal 66 MHz NanoDSP clock generator and does not require any external timing components. The device uses this internal clock for all digital control loops, ADC sampling, and UART communication-eliminating BOM cost and layout complexity associated with external crystals.
How is the high-side gate driver (HSGD) powered?
HSGD is powered by the HSVCC pin, which receives its voltage from an external bootstrap circuit: a diode and capacitor connected between the LLC half-bridge output node and HSVCC. This configuration provides isolated, self-regulating supply for the floating high-side driver, enabling direct drive of the LLC high-side MOSFET without external level-shifters or isolated supplies.
Can the MFIO pin be used simultaneously for UART configuration and PFC ROVP?
No. MFIO operates in either UART configuration mode (during programming) or PFC redundant OVP mode (during normal operation), but not both simultaneously. When configured for ROVP, the pin monitors voltage via external BSS127 transistor and triggers immediate PFC shutdown if threshold exceeds OTP-set value-providing hardware-level safety backup independent of digital control loop.
