Product details
Overview
MIC23250-GFHYMT-TR from Micrel is a dual-channel synchronous buck regulator delivering 400mA per output at fixed voltages of 1.575V and 1.8V, operating at 4MHz switching frequency with HyperLight Load™ mode for ultra-fast transient response and high light-load efficiency. It integrates two independent PWM controllers in a 10-pin 2mm × 2mm Thin MLF® package and targets core voltage regulation in space-constrained portable electronics.
For engineers reviewing the MIC23250-GFHYMT-TR datasheet, MIC23250-GFHYMT-TR pinout, MIC23250-GFHYMT-TR application, or MIC23250-GFHYMT-TR equivalent, this page delivers verified specifications, validated pin functions, confirmed dual-output timing behavior, real-world efficiency curves at 1.575V/1.8V, and cross-referenced alternatives suitable for battery-powered handheld systems requiring sub-1mm profile power solutions.
Technical Context
The MIC23250-GFHYMT-TR implements a proprietary HyperLight Load™ control architecture combining minimum-on/off-time PFM operation at light loads (≤70mA) and fixed-frequency 4MHz PWM above threshold, enabling >85% efficiency at 1mA and up to 94% peak efficiency. Its dual independent channels share no internal feedback path-each uses dedicated SNS pins for output sensing and EN pins for independent enable control.
Each channel features integrated PMOS/NMOS synchronous switches with 0.6Ω/0.8Ω typical ON-resistance, operates across 2.7V–5.5V input, supports 1µH inductors and 4.7µF ceramic output capacitors, and maintains ±2.5% output voltage accuracy over –40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion (3.0V–4.2V), USB 5V, and regulated 3.3V rails without external LDO pre-regulation. |
| Output Voltages | 1.575V and 1.8V - factory-trimmed fixed outputs; eliminates external resistor networks and reduces BOM count by two precision dividers. |
| Max Output Current | 400mA per channel - sufficient to power ARM Cortex-A/M cores, DDR I/O, or dual-band RF ICs in compact mobile platforms. |
| Switching Frequency | 4MHz nominal - enables use of 1µH inductors and 4.7µF ceramic capacitors, achieving <1mm solution height with minimal EMI filtering. |
| Quiescent Current | 33µA (both outputs enabled) - extends battery runtime in always-on sensor or standby subsystems without compromising wake-up latency. |
| Output Ripple | 20mVpp in HyperLight Load™ mode; 3mV in full PWM - meets tight noise budgets for analog sensors and RF front-ends without additional LC filtering. |
| Shutdown Current | 0.01µA - ensures negligible drain during deep sleep states in portable devices with multi-week standby requirements. |
Pinout & Package
Package: 10-pin 2mm × 2mm Thin MLF® (exposed thermal pad, Pb-free NiPdAu finish, RoHS-compliant).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SNS1 | Sense input for VOUT1 - connects directly to 1.575V output node; enables accurate regulation despite PCB trace resistance or load placement. |
| 2 | EN1 | Enable input for Channel 1 - logic-high (>0.8V) activates 1.575V rail; must be actively driven (not floating) to prevent erratic startup. |
| 3 | AGND | Analog ground reference - separates low-noise bias circuitry from high-current power return; requires separate low-impedance connection to PGND at single point. |
| 4 | SW1 | Switch node for Channel 1 - drives external 1µH inductor; high dv/dt demands short, wide routing away from sensitive analog traces. |
| 5 | PGND | Power ground return - carries pulsed inductor current for both channels; must be solid copper plane under IC with multiple vias to inner-layer ground. |
| 6 | VIN | Main power input - supplies both MOSFET bridges; requires ≥2.2µF ceramic bypass capacitor placed within 2mm of pin and PGND. |
| 7 | SW2 | Switch node for Channel 2 - drives second 1µH inductor; shares same layout constraints as SW1 but routed independently to avoid coupling. |
| 8 | AVIN | Analog supply input - powers error amplifiers and reference; tied externally to VIN but decoupled with 0.01µF capacitor near pin to suppress switching noise. |
| 9 | EN2 | Enable input for Channel 2 - logic-high (>0.8V) activates 1.8V rail; allows independent sequencing (e.g., VDD_IO before VDD_CORE) via MCU GPIO. |
| 10 | SNS2 | Sense input for VOUT2 - connects directly to 1.8V output node; enables tight regulation for memory interfaces or digital baseband ICs. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load™ mode | Enables pulse-frequency modulation below ~70mA load per channel, maintaining >85% efficiency at 1mA while delivering ultra-fast load transient recovery (<10µs). |
| Dual independent enable control | EN1 and EN2 allow staggered power-up/down sequencing-critical for SoC boot order compliance and avoiding back-powering of unpowered domains. |
| Integrated synchronous MOSFETs | Eliminates external diodes and reduces conduction loss by 30–40% vs. asynchronous designs; 0.6Ω PMOS / 0.8Ω NMOS ON-resistance minimizes thermal rise at 400mA. |
| Ultra-low output ripple | 20mVpp (PFM) and 3mV (PWM) ripple enables direct powering of noise-sensitive analog circuits (e.g., ADC references, PLL VCOs) without post-regulation LDOs. |
| Thermal performance | 70°C/W θJA in 2mm × 2mm Thin MLF® package allows full 400mA/channel operation at +85°C ambient with no heatsink or airflow required. |

FAQ
What is the exact output voltage configuration of MIC23250-GFHYMT-TR?
The MIC23250-GFHYMT-TR provides factory-trimmed fixed outputs of 1.575V on Channel 1 and 1.8V on Channel 2. These values are laser-trimmed during production and do not require external resistors-ensuring ±2.5% accuracy across temperature and load without calibration overhead. The marking code "WV1" on the device confirms this specific dual-voltage variant.
Does MIC23250-GFHYMT-TR support independent power sequencing between its two outputs?
Yes, MIC23250-GFHYMT-TR supports fully independent sequencing via dedicated EN1 and EN2 pins. Driving EN1 high before EN2 enables 1.575V core power to stabilize prior to enabling the 1.8V I/O rail-meeting strict SoC boot requirements. Each enable threshold is guaranteed between 0.5V and 1.2V, with leakage <2µA, allowing direct GPIO control without level-shifting.
What inductor and capacitor values are validated for MIC23250-GFHYMT-TR in production designs?
MIC23250-GFHYMT-TR is validated with 1µH shielded power inductors (e.g., Murata LQM31PN1R0M00, 1.2A, 120mΩ) and 4.7µF X5R ceramic capacitors (e.g., TDK C1608X5R0J475K, 6.3V, 0603). This combination achieves <1mm height, 94% peak efficiency at 400mA, and 3mV output ripple in PWM mode-per Micrel's M9999-061110-E reference design.
How does HyperLight Load™ mode affect transient response in MIC23250-GFHYMT-TR?
In HyperLight Load™ mode (active below ~70mA per channel), MIC23250-GFHYMT-TR uses minimum-on/off-time PFM control to maintain regulation with ultra-fast transient response-typically <10µs recovery from 10mA to 100mA load steps. This outperforms standard PFM controllers by eliminating frequency foldback and preserving bandwidth during light-load operation.
Is MIC23250-GFHYMT-TR compatible with lead-free reflow profiles and RoHS requirements?
Yes, MIC23250-GFHYMT-TR uses a Pb-free NiPdAu lead finish and Halogen-Free mold compound in its 2mm × 2mm Thin MLF® package. It is qualified for JEDEC J-STD-020D MSLE Level 3 (260°C peak) and fully compliant with EU RoHS Directive 2011/65/EU and China RoHS.
