Brief Description The ZSPM4012B is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The 1MHz switching frequency enables using small filter components, resulting in reduced board space and reduced bill-of-materials costs. The ZSPM4012B utilizes current mode feedback in normal regulation pulse-width modulation (PWM) mode. When the regulator is disabled (EN pin is low), the ZSPM4012B draws less than 10µA quies- cent current. The ZSPM4012B integrates a wide range of protection circuitry, including input supply under- voltage lockout, output voltage soft start, current limit, VOUT over-voltage, and thermal shutdown. The ZSPM4012B includes supervisory reporting through the PG (Power Good) open drain output to interface other components in the system. Features Output voltage options (depends on order code): Fixed output voltages: 1.5V, 1.8V, 2.5V, 3.3V, or 5V with +/- 2% output tolerance Adjustable output voltage range: 0.9V to 5V with +/- 1.5% reference Wide input voltage range: 4.5V to 24V 1MHz +/- 10% fixed switching frequency 2A continuous output current High efficiency – up to 95% Current mode PWM control with pulse- frequency modulation (PFM) mode for improved light load efficiency Voltage supervisor for V OUT reported at the PG pin Input supply under voltage lockout Soft start for controlled startup with no overshoot Full protection for over-current, over- temperature, and VOUT over-voltage Less than 10µA in Disabled Mode Low external component count Benefits Increased battery life Minimal external component count (3 capacitors, 1 inductor) Inherent fault protection and reporting Available Support Evaluation Kit Documentation Physical Characteristics Junction operating temperature -40°C to 125°C Packaged in a 16pin QFN (3x3mm) Related ZMDI Products ZSPM4011B/ZSPM4013B: 1A/3A synchronous buck converters, available with adjustable out- put from 0.9 to 5V or fixed output voltages at 1.5V, 1.8V, 2.5V, 3.3V, 5.0V (16-lead 3x3mm QFN) ZSPM1000: >5A single-phase, single-rail, true digital PWM controller (24-pin 4x4mm QFN) ZSPM4012B Application Circuits VOUT Adjustable Output VSW VCC FB BST VCC PG PG RTOP RBOT 10 k Ω (optional) VOUT EN EN CBYPASS LOUT COUT CBST VOUT Fixed Output EN VSW VCC FB VCC EN PG PG 10k Ω (optional) VOUT BST CBYPASS CBST COUT LOUT |
