Product details
Overview
MIC23150-CYMT-TR from Micrel is a 4MHz synchronous buck regulator delivering 2A output with HyperLight Load® mode, designed for ultra-efficient core voltage regulation in portable electronics. It operates from 2.7V–5.5V input, delivers fixed 1.0V output, achieves 93% peak efficiency and 23µA quiescent current, and fits in an 8-pin 2mm × 2mm Thin DFN package for space-constrained mobile power rails.
For engineers reviewing the MIC23150-CYMT-TR datasheet, MIC23150-CYMT-TR pinout, MIC23150-CYMT-TR application, or MIC23150-CYMT-TR equivalent, key selection criteria include light-load efficiency (87% at 1mA), ultra-low output ripple (14mVpp in HyperLight Load mode), thermal shutdown (160°C), and compatibility with 0.47µH inductors and 2.2µF ceramic output capacitors.
Technical Context
The MIC23150-CYMT-TR implements a proprietary minimum-on/off-time control architecture enabling seamless transition between discontinuous conduction mode (PFM) below ~120mA and continuous conduction mode (PWM) at 4MHz above that threshold. Its dual-MOSFET synchronous topology uses PMOS high-side and NMOS low-side switches with 0.15Ω/0.11Ω typical ON-resistance.
Feedback is sensed via dedicated SNS pin for accurate regulation, while separate AGND and PGND pins isolate analog biasing from high-current switching paths. The device integrates soft-start (115µs), undervoltage lockout (2.55V typ), and overtemperature protection (160°C with 20°C hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion, USB, and regulated 3.3V/5V rails without pre-regulation. |
| Output Voltage | Fixed 1.0V - factory-trimmed for processor core supply with ±2.5% accuracy across temperature and load. |
| Max Output Current | 2A - sufficient for ARM Cortex-A/M cores and FPGA I/O banks in compact form factors. |
| Switching Frequency | 4MHz - enables use of sub-1µH inductors and <1mm solution height with minimal EMI filtering. |
| Quiescent Current | 23µA - extends battery life in always-on subsystems such as GPS or Bluetooth co-processors. |
| Output Ripple | 14mVpp in HyperLight Load mode - maintains clean supply for noise-sensitive RF/analog blocks without large bulk capacitance. |
| Shutdown Current | 0.01µA - ensures near-zero drain during deep sleep states in handheld devices. |
Pinout & Package
Package: 8-pin 2mm × 2mm Thin DFN (TDFN) with exposed thermal pad; RoHS-compliant, Pb-free NiPdAu lead finish; θJA = 90°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - SW | Power Switch Node | Connects directly to inductor; carries high di/dt PWM current - requires short, wide trace routing away from sensitive nodes. |
| 3 - EN | Enable Input | Logic-compatible control (0.8V threshold); pulls device into 0.01µA shutdown when low - must not float. |
| 4 - SNS | Voltage Feedback Sense | High-impedance Kelvin connection to VOUT near output capacitor - critical for load regulation accuracy. |
| 5 - AGND | Analog Ground Reference | Return path for internal error amplifier and reference - must tie to star ground point, isolated from PGND loop. |
| 6, 7 - VIN | Power Input Supply | Accepts 2.7–5.5V; requires ≥2.2µF ceramic bypass cap placed adjacent to pins 6/7 and PGND. |
| 8 - PGND | Power Ground Return | High-current return for MOSFET switching - forms tight loop with VIN and SW; separate from AGND plane. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load® Mode | Proprietary PFM/PWM hybrid control enabling 87% efficiency at 1mA and ultra-fast transient response without external compensation. |
| Ultra-Small Solution Size | Supports 0.47µH inductor and 2.2µF output capacitor - total PCB footprint <15mm² and height <1mm. |
| Integrated Protection | Thermal shutdown (160°C), cycle-by-cycle current limit (2.2A min), and UVLO prevent fault-induced damage during startup or overload. |
| Low-Noise Regulation | 5mVpp ripple in full PWM mode and 14mVpp in HyperLight Load mode - eliminates need for post-LDO filtering in RF sections. |
| Soft-Start Function | 115µs controlled ramp-up prevents inrush current and output overshoot - no external components required. |

FAQ
What is the output voltage of the MIC23150-CYMT-TR?
The MIC23150-CYMT-TR is a fixed-output buck regulator with a nominal output voltage of 1.0V. This value is factory-trimmed and specified with ±2.5% accuracy over –40°C to +125°C junction temperature, 2.7V–5.5V input, and 20mA–500mA load conditions. The MIC23150-CYMT-TR does not support adjustable output; other variants (e.g., MIC23150-4YMT) provide different fixed voltages.
Does the MIC23150-CYMT-TR require external compensation components?
No, the MIC23150-CYMT-TR is internally compensated and designed to be stable with standard 0.47µH–2.2µH inductors and ≥2.2µF X5R/X7R ceramic output capacitors. No external RC networks or compensation pins are needed - simplifying layout and reducing BOM count. The MIC23150-CYMT-TR's control loop is optimized for this passive component range per the datasheet's stability validation.
What is the maximum recommended PCB temperature rise for the MIC23150-CYMT-TR?
The MIC23150-CYMT-TR has a maximum junction temperature of +125°C and thermal resistance θJA = 90°C/W in the 2mm × 2mm TDFN package. Assuming ambient temperature of 85°C, the allowable temperature rise is 40°C - corresponding to ≤444mW power dissipation. Proper thermal pad soldering to a ≥40mm² copper pour is required to achieve this rating. The MIC23150-CYMT-TR includes thermal shutdown at 160°C with 20°C hysteresis for safety margin.
Can the MIC23150-CYMT-TR operate with a 0.47µH inductor?
Yes, the MIC23150-CYMT-TR is explicitly characterized and qualified for use with inductors as low as 0.47µH - enabling minimal solution height (<1mm) and faster transient response. At 0.47µH, peak inductor current increases, so the selected inductor must sustain ≥2.2A saturation current. The MIC23150-CYMT-TR's current limit is 2.2A (min), ensuring safe operation with properly rated magnetics.
Is the MIC23150-CYMT-TR RoHS-compliant and halogen-free?
Yes, the MIC23150-CYMT-TR uses a GREEN, RoHS-compliant 2mm × 2mm Thin DFN package with NiPdAu lead finish and halogen-free mold compound. This compliance is confirmed in Micrel's ordering information table and package notes (Revision 2.1, February 2015). The MIC23150-CYMT-TR meets JEDEC J-STD-609A Class 1 for halogen content and EU RoHS Directive 2011/65/EU.
