Overview
| Topology | Buck Converter |
| Input voltage | 2-5.5 V |
| Switching frequency | 1500 kHz |
| Output 1 | 0.2 A |
| IC revision | 1.0 |
Description
The MP28200 is a monolithic power-management unit containing 200mA, high-efficiency, step-down, switching converters. The nanoamp quiescent current provides extremely high efficiency when the load current is down in the μA range. With minimum input voltage as low as 2V, the MP28200 allows the system to operate directly from the battery.
Features
Ultra-Low Iq: 500nA
- Wide 2.0V to 5.5V Operating Input Range
- 7 Selectable Output Voltages
- Up to 200mA Output Current
- 1.5MHz Switching Frequency in ContinuousConduction Mode (CCM)
- 100% Duty Cycle in Dropout
- 0.25Ω and 0.25Ω Internal Power MOSFETSwitches
- Cycle-by-Cycle Over-Current Protection(OCP)
- Short-Circuit Protection (SCP) with HiccupMode
- Over-Temperature Protection (OTP)
- Available in a QFN-12 (2mmx2mm)Package
Typical applications
- Battery-Powered Devices
- IOT
- Wearables/ Portable Instruments
