Product details
Overview
HR1213GY-0000-Z from Monolithic Power Systems is a multi-mode PFC and current-mode LLC combo controller supporting AC/DC inputs, featuring digital average current control (CCM/DCM), adaptive dead-time adjustment (ADTA), capacitive mode protection (CMP), and UART-configurable bias options. It delivers up to 240W in ATX/gaming PSUs with integrated 600V high-side gate driver, internal HV start-up current source (7.9–12.5mA), and dual-stage protection including OVP, OCP, OPP, and thermal shutdown.
For engineers reviewing the HR1213GY-0000-Z datasheet, HR1213GY-0000-Z pinout, HR1213GY-0000-Z application, or HR1213GY-0000-Z equivalent, this controller enables precise digital optimization of PFC efficiency across load range (up to 250kHz) and LLC stability (up to 500kHz steady-state), with configurable burst/skip modes, soft-start, brown-in/out, and external protection interface via SO pin.
Technical Context
The HR1213 employs a patented digital average current control scheme for hybrid CCM/DCM PFC operation-CCM reduces peak MOSFET current under heavy loads, while DCM lowers switching frequency at light loads. Its current-mode LLC stage implements adaptive dead-time adjustment (ADTA) with min/max limits and capacitive mode protection (CMP) using polarity detection on CSHB to enforce zero-voltage switching (ZVS) and prevent hard-switching failure.
Three dynamic operating modes-steady state, skip, and digital frequency-controlled burst mode-are selected based on real-time load conditions. Burst mode uses configurable soft switching to reduce audible noise and switching losses, while UART interface enables runtime configuration of bias settings, protections, and timing parameters without hardware changes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PFC+LLC combo controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28070 | Analog CCM-only PFC + external LLC controller; no integrated UART, ADTA, or digital burst mode; requires discrete gate drivers. | Lacks digital light-load optimization and ZVS assurance; suitable only for cost-sensitive, fixed-line applications without acoustic constraints. | Select UCC28070 only if design targets ≤150W, uses legacy analog control, and does not require burst-mode noise reduction or field configurability. |

FAQ
What is the purpose of the CSHB pin and how does it enable capacitive mode protection?
The CSHB pin senses half-bridge primary current polarity to prevent capacitive mode operation. When voltage on CSHB exceeds +80 mV (VCSNR), the IC terminates LSG; when below –80 mV (VCSPR), it terminates HSG. This ensures zero-voltage switching (ZVS) is maintained across all load and line conditions, avoiding hard-switching stress on MOSFETs.
Can HR1213GY-0000-Z operate without an external VCC supply?
Yes. The internal HV start-up current source (7.9–12.5 mA) charges VCC directly from the rectified AC line via the HV pin, eliminating the need for an external start-up resistor or auxiliary winding. Once VCC reaches 21.5 V, the IC transitions to normal operation and disables HV charging.
How does the UART interface affect system design and reliability?
The UART interface enables runtime configuration of burst frequency, soft-start time, brown-in/out thresholds, and protection trip points-reducing design iterations and enabling firmware-based tuning. It is half-duplex, internally pulled up to 3.3 V, and must be grounded when VCC drops below 14.4 V to prevent spurious communication.
What is the function of the ADTA feature and how is it implemented?
Adaptive dead-time adjustment (ADTA) monitors the SW node slew rate (≥85 V/µs) to dynamically adjust HSG/LSG timing, ensuring ZVS across varying load and input conditions. It uses internal comparators and digital logic-not external components-to minimize dead-time without risking shoot-through or capacitive conduction.
Does HR1213GY-0000-Z support DC input operation, and how is it configured?
Yes. DC input operation is enabled by configuring the BI/BO (brown-in/brown-out) DAC via UART to disable ACIN monitoring. The controller then relies solely on VCC and FBP feedback for regulation, supporting DC inputs from 12 V to 375 VDC-ideal for battery-backed or renewable energy systems.
How does the digital average current control improve PFC performance compared to analog methods?
Digital average current control enables precise hybrid CCM/DCM operation: at heavy loads, it operates in CCM to reduce peak MOSFET current and conduction loss; at light loads, it switches to DCM to lower switching frequency and improve efficiency. This yields >98% PFC efficiency across 10–100% load range-unachievable with fixed-mode analog controllers.
What thermal management considerations apply to the SOIC-20 package?
The SOIC-20 package has θJA = 65 °C/W (4-layer PCB). At 240W output, typical power dissipation is ~1.2 W; junction temperature rise is ~78 °C above ambient. To stay within 125 °C TJ max, keep ambient ≤47 °C or add copper pour under PGND/GNDD pins and use thermal vias to inner layers.
